I have build a form in which you can add images. Unfortunatelly, I am not able to call "move_uploaded_file" in PHP, as the server is running PHP safe mode and there is no way to modify this (I have checked). Therefore, I submit my form to my OWN server, which handles the file uploading.
On my own server, the file however; is not found. I think it has to do with the form calling the external url.
I know this because
echo $_FILES['uploadFile']['name'] ."<br>";
returns just an empty line.
The form itself is:
<form action="http://ejw.patrickh.nl/load.php" method="get" enctype="multipart/form-data" onsubmit ="return checkInput();"> </form>
and contains several input buttons.
Bottomline: the form on my own server submits the file perfectly, however when I make use of the form which is on another site, with the above action; no file is found.
Can this be fixed, and if so; how?
Thanks in advance!
You have to use method="post" to submit files.
Also the enctype attribute alone can be used only, if method="post".

We currently have a site that provides webforms. (podio.com)
These webforms are limited, as it does not provide conditional formatting.
(ex. Selecting option A, unhides field 1,2,4 to fill out or
Selecting option B, unhides field 1,4,6 to fill out.)
My solution: I created a php webform, with the same fields, and im able to control conditionals this way. I then just POST the variables to the other site/webform and it submits the form.
Works Great!
Now the issue is attachments.
So my question is: How would i go about pushing an attachment from my new form to the other form so it actual is submitted?
My current code for the attachment:
<input type="file" name="attachments[]" value="" accept="" data-reactid=".0.1.1.0:$0.0">
This obviously lets them chose a file, but how would i go about carrying this attachment to the actual webforms 'choose file upload' field, so it submits with the other data?
Please let me know if i need to explain more.
change this line
<form class="contact100-form validate-form" action="/infotech/webforms/tickets/results.php"
method="post" name="it_webform">
to this
<form class="contact100-form validate-form" action="/infotech/webforms/tickets/results.php"
method="post" name="it_webform" enctype="multipart/form-data">
as Clint pointed out, this needs to be there. This is infact required on ANY form that is expected to send files, without this enctype attribute, the form is just basic text for all the server cares and the files array is not sent.
Maybe like this : you can't use a local image in your second form, because the file is not stored on the user computer. but when you receive the first form : encode the image in base64 and use it in second generated form
1) use <img src = "data:image/png;base64, xxxxxx" . to display image
2) use a hidden field with value="xxxxxx..." to send to 2nd script
note : the picture cannot be changed.
you can add a option (input check box) "choose another file" to allow picking another local file, then the script check if it should handle the first picture
(base 64 encoded) or the new picture, according the "choose another file" check box value
I am trying to pre-fill my form with data that is found in my .php file. Please, what am I doing wrong? The form field displays exactly what is found in between quotes.
<form id='registration' method="POST" action="m.php" >
Username:<br><input type="read-only" name="username" value="<?php echo htmlspecialchars($ss); ?>" /><br>
This is the .php file
<?php
session_start();
if($_SESSION["logged_in"] == true){
$ss=$_SESSION['username'];
}
else $ss="nu";
?>
The file containing the form html code should also be named and executed as php (and have the .php extension alongside the other one). Otherwise php doesn't get executed inside the html code and you end up with php code sent as-is to the browser.
The action attribute is used to inform the browser what page (or script) to call once the "submit" button is pressed, this is why you are not loading the username
You need to add that php script into the page the form is on as opposed to adding it to the forms processing functionality.
Here is a read on the action attribute
https://www.sitepoint.com/action-html-attribute/
let me know if I can be of further assistance but that change should get you up and running.
I´ve a multipart form with a mixture of default inputs (text, select etc.) and a file upload (<input type="file">).
I´m using a combination of form validation class and upload library of Codeigniter for form submission. That works great.
I´ve only one problem for what I haven´t found a solution yet: If the user selects an image but misses to fill another required field (like "name"), then the form validation class blocks the request and shows an error message to the customer.
But now I´ve the problem, that the image was already submitted successfully and I don´t want to let the user add the file again. So I want to pre-fill the file input with this data.
I´ve tried different things like:
<input type="file" name="image" value="<?php echo set_value('image','');?>" />
and also spent time on finding a solution on the web but without success.
On the server side, you do not get any information about where the file is located on the client's computer, so in the scenario of a user uploading an image successfully but the user hasn't filled out the rest of the fields properly, you have to simply omit the input type="file" field entirely but keep a store of where the file is located on your server. There's a few ways to go about this, but it all involves taking the absolute location of the uploaded file and:
Inserting it back as a hidden value using <input type="hidden" name="uploadedFile" value="<?php echo $absPath; ?>" /> then checking for the existence of $_POST['uploadedFile'] and utilizing it appropriately. But this isn't a solid idea as you're now exposing server paths to the end-user (opens yourself up to malicious attack.)
Starting a session and saving the absolute path in the $_SESSION variable while presenting the user with a simple token in their re-attempt form.
I'd stick with method 2, so assuming you've done all the work to validate the form and upload the file and your file is located in $absFilePath, you could do the following:
session_start(); // This needs to be at the very top of you PHP file
// ...
$formToken = md5(time());
$_SESSION['uploadedFile'][$formToken] = $absFilePath;
Then render the token as a hidden variable using:
if (!empty($_SESSION['uploadedFile'][$formToken]))
echo '<input type="hidden" name="formToken" value="'.$formToken.'" />';
and hide the file upload portion using
if (empty($_SESSION['uploadedFile'][$formToken]))
echo // <input type="file" output here...
finally inside of your form submission code check for the existence of a formToken value before attempting to load $_FILES['image'] using isset($_POST['formToken']), and handle it using:
$absFilePath = $_SESSION['uploadedFile'][$_POST['formToken']];
Bam! Now you have your absolute file path as if the file had been uploaded just like before.
Since you haven't given enough code, I can only given you enough instruction to get you started, but this should be more than enough.
I need help with my form. There's a mix of input, textarea and file upload that i want to enter into the database..
What do I use in the ? Do I use the normal form attribute :
<form action="" method="">
or
<form enctype="" action="" method="">
Please have it in mind that, I have to do this in a single page, and the picture upload must be done along with other text input.
Thanks for your time.
You must use enctype="multipart/form-data" for file uploading, this will also work fine for non-file upload forms.
You need to set enctype="multipart/form-data" and use method="post" for any form that includes a file input. This won't stop you from including other types of fields.
(The way those fields will be submitted to the server will change, but your form parsing library will deal with the differences automatically, you only need to worry about them if you are parsing the raw input yourself).
<form enctype="multipart/form-data" method="post" action="submit.php">
submit.php being, in this case, the external PHP script that will process your form ( if you decide to use PHP ). But you can name the .php script whatever you like ( e.g. cats.php ).
The uploaded file/image data will be stored inside $_FILES, and all the textfield, textarea, radio buttons, check boxes and other data will reside inside the $_POST superglobal.
When submit.php receives the submitted form you can do all kinds of processing on it such as validating that user has submitted the correct type of file/image, store the file path of the file/image in your local database( client/server or file system based ), and much more.
Make sure to validate user input client side and server side too.
<form enctype="multipart/form-data" action="yourpage.php" method="post">
You'll need the enctype attribute if you want the file upload to work. FYI, a form can contain every field type, including file uploads, and work just fine.
In Classic ASP I had to access my textfield as load.getFileData("textfield")
instead of the standard Request("textfield") when using the enctype="multipart/form-data"
In simplest terms, I have a file select form which allows for multiple files to be selected for upload:
<form enctype="multipart/form-data" method="post" id="image_upload_form">
<input type="file" multiple="multiple" id="image_upload" name="files_to_upload[]" onchange="ini_image_upload();" />
</form>
Once files are selected, I run a quick Ajax call to check the database if certain files have already been uploaded, make sure there's no invalid files, etc. and create an array of files that already exist/I don't want to upload.
Now, I am trying to REMOVE these unwanted, scummy files from my upload array (before the actual upload IE. form gets submitted).
How do I achieve this majestically feat?
I have one suggestion for you. It is better to use below for your
requirement for upload. Have a look onto below URL.It is really so easy to integrate into your existing system and lots of features available.
http://www.uploadify.com/
what are you going to validate files by? are you trying to remove files with like some tricky extenstions like .php, .asp, .aspx ? if so then in the form element you should add a onSubmit attribute and call a function from there. then in the function check all the file names and process them and remove them from the array then replace the upload array and then return true. it would submit the form.. I actually don't know how u can retrieve the filenames form the upload array but Im pretty sure that this solution should work.
good luck!
