I have a trouble with file-uploding. Here is my part of the form:
<input type="file" name="image_file" />
<input type="submit" name="add_new" value="Upload" />
And in script i have a code:
print_r($_FILES);
After image choosing and sending form, I have an empty array $_FILES. Why?
The form must be set like this:
<form action="myuploadpage.php" method="post" enctype="multipart/form-data">
...
</form>
So that the browser knows to send the image along with the data.
Have you set the form method to POST data to the PHP script and set the action to point to it? If so then you should be able to get something like $_FILES['image_file']['name']

I have a form in my webpage,
The form uploads a file to my server.
currently when the file upload form submits, after the server side finishes saving the image it tries to redirect my webpage to a different page :( (the name of the form action)
is there a way to execute the form without the redirect part? like an ajax call for uploading my image?
thanks.
here is the form:
<form method="POST" action="/project/upload"
enctype="multipart/form-data">
Please select a file to upload : <input type="file" name="file" />
<input type="submit" value="upload" />
</form>
EDIT - Let me try to rephrase it:
is it possible to submita form in such a way that it wont change my page or redirect?
and is it possible to create a call back when it finishes?
You can use target="iframeName" on your form to get it to post to an iframe on the page with no reloads occuring. Something a little like this:
<form method="POST" action="/project/upload"
enctype="multipart/form-data" target="myFrame">
..Form content..
</form>
<iframe name="myFrame" height=0 width=0></iframe>
Think best way is using a php page which calls itself with no redirect:
<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post">
....
</form>
So you call the same page to do upload and don't need redirect. In other way you can add header in php page "/project/upload" with automatic redirect to put after upload code:
header("location: yourpage.html");
I want to use a button to link to a page. However, the page url is something like domain.com/page?action=register.
I really need this action added to my:
form action="domain.com/page?action=register"
Form attribute, but when I try it with these settings, it will only go to domain.com/page
I've tried encoding the ? into %3F but that doesn't work.
Any help?
The ? values are set by the form, as long as the form's method is set to "get" (rather than "post", which doesn't submit the values in the URL). So, if you want to submit a form to page?action=register, you'd do the following:
<form action="domain.com/page" method="get">
<input type="hidden" name="action" value="register">
It will also pass the other form values along in the URL, creating something like:
domain.com/page?action=register&first_name=john&last_name=doe
EDIT: As #ninetwozero mentioned in a comment, the scenario you describe above should work:
<form action="domain.com/page?action=register" method="post">
[rest of form]
I just tested the above and it passed both the ?action=register and the form values from my form. So, whichever you prefer.
Is "domain.com/page" the page that has the form and button?
Make sure that your button is like this:
<input type="submit" />
Not
<input type="button" />
Otherwise, you could actually use input type "button" with a javascript redirect.
<input type="button" onclick="location.href="domain.com/page?action=register" />
In fact, why use a bunch of form elements if all you want is a button to send you to another url?
<form>
<input type="button" onclick="location.href="domain.com/page?action=register" />
</form>
Not sure if you even need the tags really. Try it.
I am working on a Django project, in which a template login.html has code like -
<form name="input" action="welcome.html" method="get">
--------------SOME FORM ELEMENTS-----------------
<input type="submit" value="Login" />
</form>
When I click on Login, I want URL to be -
http://127.0.0.1:8000/welcome.html
or
http://127.0.0.1:8000/welcome.html?xxxxxxxxxxxxxxxxxx
but url comes out to be
http://127.0.0.1:8000/login.html/welcome.html?xxxxxxxxxxxxxxxxxx
(that is, "action" from form gets appended to the URL instead of getting appended to the domain) where "xxxxxxxx" stands for query submitted through form.
How can I achieve this?
<form name="input" action="/welcome.html" method="get">
You should set the action to be "/welcome.html".
thats really wired, try making your action="/welcome.html"
I want visitors to my website to be able to search for airport lounges offered by a company called Priority Pass. I have created the following form:
<form action="http://prioritypass.com/lounges/lounge-print.cfm" method="post">
<input type="text" id="print_airport_code" name="print_airport_code" value="MAN" />
<input type="submit" value="Submit" />
</form>
Which mirrors the form they have on their own mobile search site (here). But when I submit my form it doesnt seem like the parameters are being posted properly.
Any help would be great. Thanks.
The form on their website doesnt appear to contain any fields which I have missed?
You're pointing to the wrong URL; POSTing to /lounges/lounge-print.cfm is producing an HTTP redirect header, which is corrupting your output.
Additionally, the name of your input field is incorrect. Using someone else's form results often requires you to maintain all field names consistently as they appear on the remote site.
Change the form to:
<form action="http://www.prioritypass.com/mobile/lounges.cfm" method="post">
<input id="Airport_Code" name="Airport_Code" type="text" size="10" value="MAN" />
<input type="submit" value="Submit" />
</form>
Ok I really didn't know how else to sum it up for the title. I need to create a form where a user can specify an existing file, but I don't need to upload it (it's on a shared server already accessible) -- I just need to grab the filename and save it in the database so it's linked to other data.
I thought about the input tag as it provides a convenient already done interface to the user's filesystem, but I don't know if it's possible to use it without the acutal upload (leaving out enctype="multipart/form-data" doesn't seem to work). Can I tweak this to make it work, or is there any way to do it other than writing a custom mini file browser?
EDIT: I need the full path name of the file, asking the users to enter it is out of the question...
You could place the <input type="file"> outside your HTML form, and then use the onChange event to fill an <input type="hidden"> within the form that gets posted:
<input type="file"
onchange="document.getElementById('hidden_file').value = this.value;" />
<form method="POST">
<input type="hidden" id="hidden_file" value="" />
<input type="submit" />
</form>
