Quick Question: Form Validation (Newbish)

webmaster1 · November 17, 2008

Hi Freaks!

I've just finished building a form consisting of text and file input fields. I have a second file that the form is posted to that sends the input to a mySQL database.

I've fished around Google but I don't know whether to use CLIENT SIDE (javascript) or SERVER SIDE (php). What I do know is that I want the validation to occur on the form page BEFORE THE FORM ACTUALLY POSTS and I don't want to use alert boxes either.

Can anybody show me a quick example of the mechanics of form validation error messages based on the below form and included comments:

<?php
//check that just this field isn't empty
<input name="ufile[]" type="file" id="ufile[]" size="50" /></br>

//check that none of the next three fields are empty
<input name="ufile[]" type="file" id="ufile[]" size="50" /></br>
<input name="ufile[]" type="file" id="ufile[]" size="50" /></br>
<input name="ufile[]" type="file" id="ufile[]" size="50" /></br>

//check that value is numeric and contains only four digits but no comma or euro symbol
<input type="text" name="number" id="number" class="text"></br>

//check that value contains letters only
<input type="text" name="letter" id="letter" class="text"></br>

?>

I'm not sure when or how to use striplashes, empty or isset. The above form is just an example based on what I need to know.

A useful link might also suffice.

Here is a simple way to do validation:

<?php

if ($_POST) {
// validate fields
if (count($_FILES['ufile']) < 4) {
	$errors['ufile'] = 'Error: blah blah blah';
}
if (!is_numeric($_POST['number']) or strlen($_POST['number']) != 4) {
	$errors['number'] = 'Error: blah blah blah';
}
if (!preg_match('/^[\w]*$/',$_POST['letter'])) {
	$errors['letter'] = 'Error: blah blah blah';
}

if (empty($errors)) {
	// there were no errors, do whatever you want to do here
}
}

?>

//check that just this field isn't empty
<?php echo ($errors['ufile']) ? '<div class="error">'.$errors['ufile'].'</div>' : '' ?>
<input name="ufile[]" type="file" id="ufile[]" size="50" /><br />

//check that none of the next three fields are empty
<input name="ufile[]" type="file" id="ufile[]" size="50" /><br />
<input name="ufile[]" type="file" id="ufile[]" size="50" /><br />
<input name="ufile[]" type="file" id="ufile[]" size="50" /><br /

//check that value is numeric and contains only four digits but no comma or euro symbol
<?php echo ($errors['number']) ? '<div class="error">'.$errors['number'].'</div>' : '' ?>
<input type="text" name="number" id="number" class="text"><br />

//check that value contains letters only
<?php echo ($errors['letter']) ? '<div class="error">'.$errors['letter'].'</div>' : '' ?>
<input type="text" name="letter" id="letter" class="text"><br />

That exactly what I was looking to do. Its great the way the error messages pop up in a relevant spot too.

Just two more questions on the below lines of code:

if ($_POST)

Does this mean 'when the submit button is clicked and the form is posting'?

if (empty($errors))

What exactly would I do here? I'm not sure I understand what the action is. Do I need to add additional code here to make my form post or would I just put a message in like "No errors were found"?

flyhoney · November 17, 2008

if ($_POST)

Checks to see if the form was posted. It would be better to do something like this:

if ($_POST['name_of_submit_button'] == 'Submit')

if (empty($errors))

And here is where I would actually insert the data into a database and move the uploaded files to wherever you plan to store them. Whenever you are done with the database and file upload stuff, you can either redirect to a success page or just display a success message on the same page as the form.

webmaster1 · November 17, 2008

So after the if (empty($errors)) I can just paste in all the code I thought I had to have in a seperate page?

Here's my code to process the form by the way. I know its probably messy but I'm very proud of it (newbishly of course).

PFMaBiSmAd · November 17, 2008

If you are uploading files, there is a subtle error condition that occurs when you exceed the maximum post size setting. The $_FILES and $_POST arrays are empty. The best way to detect this is if $_SERVER['REQUEST_METHOD'] == 'POST' (meaning a form or a script using the POST method submitted data to your code) and the $_FILES array is empty.

You must also test for upload errors before you attempt to access any of the uploaded file information. In the code posted so far, $_FILES["file"]["type"] is being tested before $_FILES["file"]["error"] is being tested. However, if there was an upload error, $_FILES["file"]["type"] will be empty and the code will report an "Invalid file. ...." when in fact it should report "Return Code: " . $_FILES["file"]["error"]..."

The following logic -

  if ($_FILES["file"]["error"] > 0)
  
  // CONDITION B THEN: an error return code is given

    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }

Must be executed before this logic -

if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000))

// CONDITION A THEN:

Hi PFMaBiSmAd ,

You're going to kill me but changed my code when you were in midpost. What you saw was the first rendition.

Could you shine some light on code as its posted now?

So sorry :-[

webmaster1 · November 17, 2008

Also I seem to be stuck on how or where to check if ...

$HTTP_POST_FILES['ufile']['name'][0]

$HTTP_POST_FILES['ufile']['name'][1]

$HTTP_POST_FILES['ufile']['name'][2]

... equal the same image (i.e. the user uploaded the same image more than once in the one submit)

webmaster1 · November 17, 2008

FYI I've been trying to stitch together the validation piece by piece but none of my error messages are being called on.

I tried this way as well but to avail: http://www.lotsofcode.com/php/validation.htm

Help me PHP Kenobi; you're my only hope.

webmaster1 · November 17, 2008

Sorry to flog a dead horse but can anybody help me with this?

I'm having so much difficulty trying to validate and process my form in the same page.

PFMaBiSmAd · November 17, 2008

I did not see any mention of validating uploads at that link?

The following is (tested) code that will detect and handle all possible errors associated with uploads for both a single and multiple (using an array) file uploads (change the $_FILES['file'] name field to match the name you used in your form. Edit: This would be 'ufile" in the latest code you posted.) -

<?php
if($_SERVER['REQUEST_METHOD'] <> "POST")
{
// do any special processing when this page is reached direcly by the GET method...
} else {
if(empty($_FILES))
{
	echo "The file upload failed for one or more of the following reasons -";
	echo "<ol>";
	echo "<li>Uploads are not enabled on your server in php.ini</li>";
	echo "<li>The form tag does not contain - enctype=\"multipart/form-data\" or something else about the form makes it invalid</li>";
	echo "<li>There is no type=\"file\" field in the form</li>";
	echo "<li>The total size of the data from the form exceeds the post_max_size setting</li>";
	echo "</ol>";
} else {
	if(is_array($_FILES['file']['error'])){
		// for multiple files, ['error'], ['name'], ['tmp_name'], ['size'], and ['type'] elements will be set for each type=file form field
		foreach($_FILES['file']['error'] as $key => $value){
			switch ($_FILES['file']['error'][$key]) {
				case 0:
					// echo "The file uploaded to the server OK<br />";
					break;
				case 1:
					echo "The uploaded file exceeds the upload maximum size directive in php.ini<br />";
					break;
				case 2:
					echo "The uploaded file exceeds {$_POST['MAX_FILE_SIZE']}, the MAX_FILE_SIZE directive in the HTML form<br />";
					break;
				case 3:
					echo "The uploaded file was only partially uploaded<br />";
					break;
				case 4:
					echo "No file was selected<br />";
					break;
				case 6:	
					echo "Missing temporary upload folder<br />";
					break;
				case 7:
					echo "Failed to write file to disk<br />";
					break;
				case 8:
					echo "File upload stopped by extension<br />";
					break;			
				default:
					echo "An unused error value was returned<br />";
			} // end of switch/case
			if($_FILES['file']['error'][$key] == 0){
				// the file was uploaded 
				// use the uploaded file information here
				// put any type, size, file name/extension, or content validation here
				// The following will be set for each file - 
				// $_FILES['file']['name'][$key], $_FILES['file']['tmp_name'][$key], $_FILES['file']['size'][$key], and $_FILES['file']['type'][$key]
				echo "Process the uploaded file here<br />";
			}						
		} // end of foreach loop
	} else {
		switch ($_FILES['file']['error']) {
			case 0:
				// echo "The file uploaded to the server OK<br />";
				break;
			case 1:
				echo "The uploaded file exceeds the upload maximum size directive in php.ini<br />";
				break;
			case 2:
				echo "The uploaded file exceeds {$_POST['MAX_FILE_SIZE']}, the MAX_FILE_SIZE directive in the HTML form<br />";
				break;
			case 3:
				echo "The uploaded file was only partially uploaded<br />";
				break;
			case 4:
				echo "No file was selected<br />";
				break;
			case 6:	
				echo "Missing temporary upload folder<br />";
				break;
			case 7:
				echo "Failed to write file to disk<br />";
				break;
			case 8:
				echo "File upload stopped by extension<br />";
				break;			
			default:
				echo "An unused error value was returned<br />";
		} // end of switch/case
		if($_FILES['file']['error'] == 0){
			// the file was uploaded 
			// use the uploaded file information here
			// put any type, size, file name/extension, or content validation here
			// The following will be set for the file - 
			// $_FILES['file']['name'], $_FILES['file']['tmp_name'], $_FILES['file']['size'], and $_FILES['file']['type']
			echo "Process the uploaded file here<br />";
		}						
	} // end of single file else statement
}
}
?>

Thanks, I'll start breaking this appart now.

The provided link only handles regular text input validation which I still can't get a handle on.

Most tutorials show me blocks of code but hardly none at all show me how it all stiches together.

(e.g. in your code I don't know what triggers the cases and how it should slot it with my code)

webmaster1 · November 18, 2008

Yay! I've done it! Well almost...

There's only two things left. Firstly how do I validate if (strlen($_POST['xxx']) > 0) for an array of three upload files (this is fixed so there won't be more or less than 3).

I've tried if (strlen($_POST['ufile[]']) > 0) but I get an error. PFMaBiSmAd's code looks great but I already validate the actual images when processing the form. All I need is a snippet of code to validate that the fields are not empty.

Secondly I'm not sure how to validate if a text area is empty since its html syntax is different from a reguler text input field

Here's the full code (please review it before answering - thanks)

<?php

Oops! Here's the text area:

<textarea name="info" rows="5" cols="50"/>
<?php if (isset($_POST['info'])) echo stripslashes($_POST['info']); ?>
</textarea>

Oops! Here's the text area:

<textarea name="info" rows="5" cols="50"/>
<?php if (isset($_POST['info'])) echo stripslashes($_POST['info']); ?>
</textarea>

Solving this portion.

<?php
if (isset($_POST['info'])) {
    $info = trim($_POST['info']);
    if ($info == "" || empty($info)) {
        $message_info = "Please enter data for info!";
   }
}
?>

Trim should trim out any whitespaces at the end/breaks and empty will check if PHP considers the variable to be empty. Untested but I am pretty sure that would work.

webmaster1 · November 18, 2008

That worked great. Thanks Premiso.

Any takers on the validating the file upload:

    <li>
    <label for "ufile[]">Image File 1:</label>
    <input type="file" name="ufile[]"  id="ufile[]"/> 
    </li>
    <li>
    <label for "ufile[]">Image File 2:</label>
    <input type="file" name="ufile[]"  id="ufile[]"/> 
    </li>
    <li>
    <label for "ufile[]">Image File 3:</label>
    <input type="file" name="ufile[]"  id="ufile[]"/> 
    </li>

I just need to check if the fields are empty.

(If you're feeling extra generous I need to check if any of them equal each other )
