I'm trying to access the following properties from the Wikidata API: id, url, aliases, description and label but so far have been unsuccessful. I'm sure I'm making basic mistakes and so far only have the following code. Any suggestions as to the best way to access this data is much appreciated.
<html>
<body>
<form method="post">
Search: <input type="text" name="q" value="Google"/>
<input type="submit" value="Submit">
</form>
<?php
if (isset($_POST['q'])) {
$search = $_POST['q'];
$errors = libxml_use_internal_errors(true);
$doc = new DOMDocument();
$doc->loadHTMLFile("https://www.wikidata.org/w/api.php?
action=wbsearchentities&search=Google&format=json&language=en");
libxml_clear_errors();
libxml_use_internal_errors($errors);
}
?>
</body>
</html>
Edit - I have managed to get a string ($jsonArr) containing particular data that I would like. However I would like to get the first instance of the particular elements from the string specifically id, url, alias, description and label i.e. specifically: variable1 - Q95, variable2 - //www.wikidata.org/wiki/Q95, variable3 - Google.Inc, varialbe4 - American multinational Internet and technology corporation, variable5 - Google/ Please see code below:
<HTML>
<body>
<form method="post">
Search: <input type="text" name="q" value="Google"/>
<input type="submit" value="Submit">
</form>
<?php
if (isset($_POST['q'])) {
$search = $_POST['q'];
$errors = libxml_use_internal_errors(true);
$doc = new DOMDocument();
$doc->loadHTMLFile("https://www.wikidata.org/w/api.php?
action=wbsearchentities&search=$search&format=json&language=en");
libxml_clear_errors();
libxml_use_internal_errors($errors);
var_dump($doc);
echo "<p>";
$jsonArr = $doc->documentElement->nodeValue;
$jsonArr = (string)$jsonArr;
echo $jsonArr;
}
?>
</body>
</HTML>
You need to show the JSON you want to parse...
Basicly you can get values out of JSON in PHP like this...
If $doc is the JSON you want to parse
$jsonArr = json_decode($doc, true);
$myValue = $jsonArr["keyYouWant"];
Edit after understanding what you are doing there :-)
Hi, Im sorry I was completely confused of what you were doing there... So I have testet your code on my server and just get what you want...
Following the code you wanted... I took clear var names, so they are a little bit longer, but easier to understand...
$searchString = urlencode($_POST['q']); //Encode your Searchstring for url
$resultJSONString = file_get_contents("https://www.wikidata.org/w/api.php?action=wbsearchentities&search=".$searchString."&format=json&language=en"); //Get your Data from wiki
$resultArrayWithHeader = json_decode($resultJSONString, true); //Make an associative Array from respondet JSON
$resultArrayClean = $resultArrayWithHeader["search"]; //Get the search Array and ignore the header part
for ($i = 0; $i < count($resultArrayClean); $i++) { //Loop through the search results
echo("<b>Entry: ".$i."</b>");
echo("<br>");
echo($resultArrayClean[$i]["id"]); //Search results value of key 'id' at position n
echo("<br>");
echo($resultArrayClean[$i]["url"]); //Search results value of key 'url' at position n
echo("<br>");
echo($resultArrayClean[$i]["aliases"]); //Search results value of key 'aliases' at position n
echo("<br>");
echo("<br>");
echo("<br>");

I need to save the image for an avatar.
Can anyone give me a simple code to save and retrieve image?
I need to:
Save image in folder
Save image name in DB
Finally retrieve on image tag; I have to do it by Query Builder
Form:
<form action="" method="post" role="form" multiple>
{{csrf_field()}}
<legend>Form Title</legend>
<div class="form-group">
<label for="">Your Image</label>
<input type="file" name="avatar">
</div>
<button type="submit" class="btn btn-primary">save</button>
back
</form>
<img name="youravatar" src="">
</div>
Route:
Route::get('pic','avatarController#picshow');
Route::post('pic','avatarController#pic');
Controller:
I have the avatarController, but it is empty because I don't know what to do.
Database:
Table name: avatar
Fields: name id, imgsrc, created_at, Updated_at
Other:
I found this code but I can't find out anything:
if ($request->hasFile('avatar')) {
$file = array('avatar' => Input::file('avatar'));
$destinationPath = '/'; // upload path
$extension = Input::file('avatar')->getClientOriginalExtension();
$fileName = rand(11111,99999).'.'.$extension; // renaming image
Input::file('avatar')->move($destinationPath, $fileName);
}
First, make sure you have the encrypt attribute in your form
<form action="#" method="post" enctype="multipart/form-data">
You can use something similar to this in your controller
public function save(Request $request)
{
$file = $request->file('file');
// rename your file
$name = $file->getClientOriginalName();
\Storage::disk('local')->put($name, \File::get($file));
return "file saved";
}
Yes, you should store the file route in your database as well.
Make sure you are using a consistent path for your images like
Finally you have to create a route to give public access to your image file, like so:
Route::get('images/{file}', function ($file) {
$public_path = public_path();
$url = $public_path . '/storage/' . $file;
// file exists ?
if (Storage::exists($archivo))
{
return response()->file($pathToFile);
}
//not found ?
abort(404);
});
Check the docs about Laravel Responses
I hope this gives you an Idea of what to do.
Upload Image in laravel 5.4
check if request has image
$request->hasFile('image')
OR
$request->file('image')->isValid()
Now Save Image
$request->inputname->store('folder-name') return image path 'folder name/created image name
$request->image->store('images')
Check if image exits
Storage::disk('local')->exists('image name');
Delete Image
Storage::delete('image');
This is my code
if ($request->hasFile('image') && $request->file('image')->isValid())
{
$path = $request->image->store('images');
if(!empty($path)){
$edit = Model::FindOrFail($id);
// Delete old image
$exists = Storage::disk('local')->exists($edit->image);
if($exists){
Storage::delete($edit->image);
}
$edit->image = $path;
$edit->save();
}
}
Reference
I tried searching but no success i want to upload max 5 images to database along with user form data.I have table where all user data of form posted is saved along with images uploaded[image upload is attached with user form] picture fields in database are named as pic1,pic2,pic3.. pic5 + email,password etc I am successfull in uploading image data to database but not images.
//controller
if ($this->form_validation->run()!=true) {
$data['countryDrop'] = $this->Country_states_cities->getCountries();
$this->load->view('header');
$this->load->view('register',$data); //Display page
$this->load->view('footer');
}else{
$form=array();
$form['first_name']=$this->input->post("first_name",true);
$form['last_name']=$this->input->post("last_name",true);
$form['dob']=date('Y-m-d',strtotime($this->input->post("dob",true)));
$form['email']=$this->input->post("email",true);
$form['password']=sha1($this->input->post("password",true));
$form['phone']=$this->input->post("phone",true);
$form['addline2']=$this->input->post("addressline2",true);
$form['zip']=$this->input->post("zip",true);
$result = $this->Couch_reg->insert_new_user($form); //call to model
//model
function insert_new_user($form)
{
$this->db->insert('tbl_usrs',$form);
if ($this->db->affected_rows() > 0) {
return true;
} else {
return false;
}
}
//view
<input type="file" name="uploadfile[]" accept = "image/*" multiple = "multiple" size="20" /> <br />
as we can see model part is very short i want to collect images name in array form and send it to database.
You need to save the images in the upload folder and save the image name in the database.
<html>
<body>
<form method="POST" action="<?php echo site_url('my-controller/file_upload');?>" 'enctype'=>'multipart/form-data'>
<label for="file">Filename:</label>
<input type="file" name="userfile[]" id="file" multiple>
<input type="submit" value="upload"></form>
</body>
</html>
Then create controller
make funtion inside it:
$files = $_FILES;
$cpt = count($_FILES['userfile']['name']);
for($i=0; $i<$cpt; $i++)
{
$_FILES['userfile']['name']= $files['userfile']['name'][$i];
$_FILES['userfile']['type']= $files['userfile']['type'][$i];
$_FILES['userfile']['tmp_name']= $files['userfile']['tmp_name'][$i];
$_FILES['userfile']['error']= $files['userfile']['error'][$i];
$_FILES['userfile']['size']= $files['userfile']['size'][$i];
$this->upload->initialize($this->set_upload_options());
$this->upload->do_upload();
$fileName = $_FILES['userfile']['name'];
$images[] = $fileName;
Hope this will help you.

i want to store API result in database
i am new to this API php coding things,
<?php
$account_id = 1122;
$api = "http://url&account_id";
$json = file_get_contents($api);
print_r($json);
?>
here is the output
{"status":"ok","count":1,"meta":{"count":1},"data":{"1122":{"statistics":{"all":{"wins":112,"losses":118},"xp":721},"nickname":"nickie"}}}
now i want to store data in variables and as well want to show in Tables.
for saving it in variables i am using this method.
$nickname = $decoded->{'data'}->{$account_id}->{'nickname'};
$max_xp = $decoded->{'data'}->{$account_id}->{'statistics'}->{'xp'};
how can i show all data in tables. or anywhere on main body page.
sorry for my bad poor programming, i am trying to so learn it.
in this case if I understand correctly, it is necessary to create an HTML form you with two text boxes, you can later send this form in a PHP page that can retrieve the values of these input fields and create the URL for the API:
An HTML page
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
<title>Your page title</title>
</head>
<body>
<div>
<form method="post" action="/your/php/file">
<div>
<label for="name" />
<input type="text" name="username" id="name" />
</div>
<div>
<label for="location" />
<input type="text" name="location" id="location" />
</div>
<div>
<button>Submit</button>
</div>
</form>
</div>
</body>
</html>
A PHP page
<?php
if (isset($_POST['username'], $_POST['location']) && !empty($_POST['username']) && !empty($_POST['location'])) {
$username = htmlspecialchars($_POST['username']);
$location = htmlspecialchars($_POST['location']);
$account_id = 1122;
$api = "http://url?account_id&username={$username}&location={$location}";
$json = file_get_contents($api);
//now you have result as associative array
$result = json_decode($json, true);
//you can do what you want now
}
?>
Try to json_decode your results like this:
<?php
$account_id = 1122;
$api = "http://url&account_id";
$json = file_get_contents($api);
//now you have result as associative array
$result = json_decode($json, true);
//print_r($result);
$nickname = $result['data'][$account_id]['nickname'];
?>
try and tell me what
Given that a page http://test.intra has the following form code:
<form>
<textarea id="description" name="description"><p>Hello</p></textarea>
<input type="submit" name="submit_save" id='submit_btn' value="Save">
</form>
description field is submitted on browser with value <p>Hello</p>
But using the following code:
$crawler = $client->request('GET', 'http://test.intra');
/* $client is a instance of \Symfony\Bundle\FrameworkBundle\Client ]
* $crawler is a instance of \Symfony\Component\DomCrawler\Crawler
*/
$domForm = $crawler->filter('form');
$domForm = $domForm->selectButton('submit_btn');
$this->client->submit($form);
description field is submited with value <p> </p>
Should client [\Symfony\Bundle\FrameworkBundle\Client] decode form data before submit is called? Am I missing something?
Thanks
I'm not totally sure what you are asking, but I noticed your code wasn't correct.
$crawler = $client->request('GET', 'http://test.intra');
$domForm = $crawler->filter('form')->form();
$crawler = $this->client->submit($domForm);
Now you'll be able to check your asserts on $crawler.
$this->assertTrue($this->client->getResponse()->isSuccessful());
Am just learning html. I need to write code that solves the quadratic equation formula. I tried php code embeding in html but am getting blank output. How do I get user values a, b, c and display conditional answers?
Here's a simple example of what you need to do. First make a HTML form:
<form method="post" action="index.php">
<input type="text" name="a" value="Enter 'a'" />
<input type="text" name="b" value="Enter 'b'" />
<input type="text" name="c" value="Enter 'c'" />
<input type="submit" name='calc' value="Calculate" />
</form>
There is your form. Now the calculations:
<?php
// Check if the form is submitted
if (isset($_POST['calc'])) {
//assign variables
$a = $_POST['a'];
$b = $_POST['b'];
$c = $_POST['c'];
//after assigning variables you can calculate your equation
$d = $b * $b - (4 * $a * $c);
$x1 = (-$b + sqrt($d)) / (2 * $a);
$x2 = (-$b - sqrt($d)) / (2 * $a);
echo "x<sub>1</sub> = {$x1} and x<sub>2</sub> = {$x2}";
} else {
// here you can put your HTML form
}
?>
You need to do more checks on it, but as I said before this is a simple example.
Edit: learn from the source , the official php site: http://php.net/manual/en/tutorial.forms.php
1.Create a form with the fields you want. <form method='post' ....>...</form>
2.The user submit the form and then write a PHP code which get the posted data ($_POST)
and manipulate it according to the quadratic equation formula.
3.Echo the result.
I have smaller example.
This file sends data from form to itself. When it sends something - result of condition
$_SERVER['REQUEST_METHOD']=='POST'
is true. If its true - server process code in "if" block. It assigns data sent from form to 2 variables, then adds them and store in "$sum" variable. Result is displayed.
<html>
<body>
<form method="POST">
<p>
A: <br />
<input name="number_a" type="text"></input>
</p>
<p>B: <br />
<input name="number_b" type="text"></input>
</p>
<p>
<input type="submit"/>
</p>
</form>
<?php
if ($_SERVER['REQUEST_METHOD']=='POST') // process "if block", if form was sumbmitted
{
$a = $_POST['number_a'] ; // get first number form data sent by form to that file itself
$b = $_POST['number_b'] ; // get second number form data sent by form to that file itself
$sum = $a + $b; // calculate something
echo "A+B=" . $sum; // print this to html source, use "." (dot) for append text to another text/variable
}
?>
</body>
</html>
You need PHP server to test/use this! PHP file must be processed by web server, which creates page. Opening php file from disk will not work. If you need more explanations - ask for it in comments.
