I am trying to create an upload script and am having issues with IE8 and older. (of course ;) ) In all other browsers it works fine but in IE8 the $_FILES array is empty. This is the html code being used:
<FORM method=post action=api/upload.php target=form8230839>
<INPUT name=file type=file>
<INPUT value="Submit Query" type=submit>
<INPUT name=id value=id66130748349062623150808191 type=hidden>
</FORM>
<IFRAME id=form8230839 name=form8230839></IFRAME>
(note the code is being generated by javascript createElement so IE8 is writing it out with the caps and lack of quotes around attributes.)
Then in the php file I am doing:
print_r($_FILES);
which returns as just an empty array? Any help would be great. Thanks!
Add enctype="multipart/form-data" to your form tag.
Spec: http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.2
Your question seems to be a possible duplicate of this one:
$_FILES array in PHP is empty
Nevertheless, as others have pointed out, and also from the attached, the solution is to add:
enctype="multipart/form-data"
to your form.

i assume this is a noob question, so sorry.
I'm trying to write this HTML-Page with a "form" that will work like a link on my raspberry pi.
So I used this code:
<form action="http://192.168.178.62/graph.pl?type=week">
<input type="submit" value="Blah" />
</form>
But instead of ending up at the adress I wrote in the code, I end up here: http://192.168.178.62/graph.pl? ("type=week" is missing, its just cut off)
Why is that, and how can I fix it?
thanks a lot!
When you submit a form with method="GET" (which is the default) then a new query string will be generated from the names and values of the successful form controls (since you don't have any, it will be empty). The new (empty) query string will replace the one in the action.
Options:
Use a link. (This is the best option. You aren't collecting any data from the user. You aren't making a POST request).
Move the data from the action to <input type="hidden" ...> elements.
I have a simple HTML form that I am building. I want to be able to added multiple files to submit with the form to upload. Everything I am reading online about HTML5 says that I am able to do this with the HTML5 Input Multiple tag. When I try this in any browser I get the standard Input with a type of file. When I inspect the DOM i see that it has only a single file in it's Files[0] attribute. Here is my form. Please let me know what I am doing wrong.
Here is my HTML for the the form for uploading files:
<form method="post" action=upload.php" enctype="multipart/form-data">
<input type="file" id="basicUploadFile" multiple >
</form>
Also. I have tried this in Chrome, Firefox, IE 11. Even going to the W3school.com demo doesn't seem to work in any of them for multiple files.
files[0] will show you the first file selected. files gives you a collection of the selected files, files.length gives you the number of files selected. So once you select more than one file if you console.log(fileinput.files) you'll see multiple files logged.
<form method="post" action="upload.php" enctype="multipart/form-data">
<input type="file" id="UploadedFiles" name="UploadedFiles[]" multiple>
<input type="submit" value="SendFile">
</form>
in upload.php analize structure of array $_FILES ;)
good like!
Is that a typo? There is a " missing before the upload.php
your form tag looks correct

[edit]
If you are referring to the W3schools site, this works for me on Chrome and IE
http://www.w3schools.com/tags/att_input_multiple.asp
TryIt site:

I have a form with <input type="submit">. In Chrome submit doesn't do anything. On a Network tab in developer tools I see nothing. No errors in developer tools either. Meanwhile, if I do save a page and open a saved page, then after I press submit button, I see something appears in Network tab. This happens in Chrome and Firefox. This works as expected in IE.
Does anybody have a hindsight, what should I look at?
I don't need a direct answer, I only need to know, where should I look at. If someone posts a direction and that'll help me to solve my problem, I'll accept it as a correct answer.
Structure of a page looks like this:
html
head
body
div
div
form
form
form
form
form
input
input
table
table
tbody
tr..td..input type=submit
If you are not using any JavaScript for form validation then a simple layout for your form would look like this:
<form action="formHandler.php" method="post">
<input name="fname" id="fname" type="text" value="example" />
<input type="submit" value="submit" />
</form>
You need to ensure you have the submit button within the form element and an appropriate action attribute on the form element is present.
For a more direct answer, provide the code you are working with.
You may find the following of use: http://www.w3.org/TR/html401/interact/forms.html
Are you using HTML5? If so, check whether you have any <input type="hidden"> in your form with the property required. Remove that required property. Internet Explorer won't take this property, so it works but Chrome will.
I faced this problem today, and the issue was I was preventing event default action in document onclick:
document.onclick = function(e) {
e.preventDefault();
}
Document onclick usually is used for event delegation but it's wrong to prevent default for every event, you must do it only for required elements:
document.onclick = function(e) {
if (e.target instanceof HTMLAnchorElement) e.preventDefault();
}
Hello from the future.
For clarity, I just wanted to add (as this was pretty high up in google) - we can now use
<button type="submit">Upload Stuff</button>
And to reset a form
<button type="reset" value="Reset">Reset</button>
Check out button types
We can also attach buttons to submit forms like this:
<button type="submit" form="myform" value="Submit">Submit</button>
Check if you are using any sort of jquery/javascript validation on the page and try disabling it and see what happens. You can use your browser's developer tools to see if any javascript file with validate or validation is being loaded. You can also look for hidden form elements (ie. style set to display:none; or something like that) and make sure there isn't a hidden validation error on those that's not being rendered.
I ran into this on a friend's HTML code and in his case, he was missing quotes.
For example:
<form action="formHandler.php" name="yourForm" id="theForm" method="post">
<input type="text" name="fname" id="fname" style="width:90;font-size:10>
<input type="submit" value="submit"/>
</form>
In this example, a missing quote on the input text fname will simply render the submit button un-usable and the form will not submit.
Of course, this is a bad example because I should be using CSS in the first place ;) but anyways, check all your single and double quotes to see that they are closing properly.
Also, if you have any tags like center, move them out of the form.
<form action="formHandler.php" name="yourForm" id="theForm" method="post">
<center> <-- bad
As strange it may seems, it can have an impact.
You can't have a form element as a child (directly or indirectly) of another form element.
If the following does not return null then you need to remove the excess form elements:
document.querySelectorAll('form form');//Must return null to be valid.
check your form is outside the table
i have a web form who send post variables like:
<form action="teacher.php" method="post">
<input name="pass" type="password">
<input name="quiere" type="image" value="submit" src="IMG/unlock-32.png" />
</from>
In the same page i check for a submit acction with php doing a simple isset check like:
"if (isset($_POST['quiere'])) {"
But if you do this in IE the post var "QUIERE" (the button var) does not post, the others vars are fine, and if you try this simple form in any other browser it works. I only get this form function well in IE changing the button for a normal button, instead of a image button like:
<input name="quiere" type="submit" value="submit" />
In this way, the var "quiere" get post. So, what do you think? and sorry for my english.
This is a known issue in IE6 and IE7. image inputs are not submitted with a form as you'd expect. It submits the cords instead and changes the field names with appending _x or _y . i've run into this several times in the past and found others have as well.
A fix is to check for $_POST['quiere_x'] or $_POST['quiere_y'] instead of just $_POST['quiere']
I believe this link has your answer.
IE doesn't send the name/value pair
for elements.
They only send the x/y coordinates.
Most, if not all, other common
browsers send both the name/value pair
and the x/y coordinates.

This is a known ie issue. Read above for the same.
Yup, just another annoying IE issue.
I normally do this:
<form action="teacher.php" method="post">
<input name="pass" type="password">
<input type="hidden" name="quiere" value="submit" />
<input type="image" src="IMG/unlock-32.png" />
</form>
i.e. - just move the name and value attributes into a hidden field.
i want to have a textarea where I can edit html code directly. After submitting the form the content if the textarea (with html tags) should be saved to a MySQL database. I use PHP to receive the date and save it to the database. My problem is, that the HTML code is not properly sent to PHP. I do not receive the HTML code but just the text. How could I fix this?
my Form looks like this:
<form method="post" enctype="multipart/form-data" action="form.php">
<textarea name="html_code">
testlink
</textarea>
<input type=submit value="submit"/>
</form>
The form.php should now be able to show the content of the textarea
echo $_POST['html_code'];
shows: testlink
I want: testlink
Thank you all for your answers. I found the problem. It was Joomla. Joomla removed HTML tags when I got strings via getVar. I had to use the mask option JREQUEST_ALLOWRAW to solve the issue.
JRequest::getVar('html_code', '', 'post' , 'STRING', JREQUEST_ALLOWRAW);
Are you echoing it into an HTML page? Because the code will be parsed into an actual link.
View the source of your output page.
You're using the wrong encoding type.
Instead of "multipart/form-data", it should be "text/plain".
You don't have to encode the data as Doug says above; but it will be encoded for you when you submit the form, so don't forget to decode before using.
Your form should be:
<form method="post" enctype="multipart/form-data" action="form.php">
<textarea name="html_code">
<a href="link">testlink</a>
</textarea>
<input type=submit value="submit"/>
</form>
(No, it's not messed up. They're called HTML entities)
You can use htmlentities() in PHP to achieve that.
