[RESOLVED] ['Submit'] Variable Only Passes on Seconde Submit

activomate

So, I've been fooling around with PHP/MySQL after a three year break and I've encountered something that I've never run across and has me completly confused.

I've created a form with a simple text box and submit button on a .html page. Upon clicking the submit button the first time, the value captured within the text box passes to the next .php page just fine. However, through various troubleshooting techniques "echo $_POST['Submit']" on the subsequent .php page, I've found that the "Submit" variable does not pass correctly (all other variables are being passed just fine!)

Now, the wierd part....when i select "back" on the browser and click the submit button again, the "Submit" variable passes just fine. I've created other .html form / .php files recently and these work just fine.

If necessary, I can post some sample code, but has anyone ever seen / heard of this happening? Thanks in advance for your help!

What do you mean by 'not passing correctly'?

The .html code that I'm utilizing to first accept the values:

<body>

<p class="style1">Add Answer:</p>
<p class="style1"> </p>
<form id="form1" name="form1" method="post" action="http://www.sampleurl.php">
<table width="49%" border="0" cellspacing="10">
<tr>
<td width="35%" height="25">Answer Text:</td>
<td width="65%"><label>
<input type="text" name="Answer" id="Answer" width="300" />
</label></td>
</tr>
<tr>
<td colspan="2"><label>
<div align="center">
<input name="Submit" type="submit" id="Submit" value="Submit" />
</div>
</label></td>
</tr>
</table>
</form>
<p class="style1"> </p>
</body>
</html>

The .php code that accepts the variables from the previous page and inserts the values into the database is...

<body>

<?php

include "../dbconnect.php";

print_r($REQUEST);
echo $POST['Answer'];
echo $_POST['Submit'];

if(isset($_POST['Submit']))

{

$Answer = $_POST['Answer'];

$query = "INSERT INTO Answer SET Answer='$Answer'";

mysql_query($query);

echo "Your answer was entered successfully";
}
else
{
echo "There was an error processing your request";
}
?>
</body>
</html>

What do you mean when you say "does not pass correctly"?

intenz-

I'm not sure if I'm stating this correctly, but it appears on my other examples(pages that are working correctly), that a value of 'submit' gets passed to the secnodary .php page.

In fact, on a successful "submit", when I echo $POST['Submit']; indeed a 'Submit' value is printed on the secondary .php page. What I was thinking is that it is this value that satisfies the if(isset($POST['Submit'])) command and allows the code to proceed through the first if statement. What appears to be happening is that this submit is not passed and therfore, the code jumps down to the else clause and nothing is inserted into the database.

If you could url me and show me, then I may be more assistant.

I believe that I may have narrowed down my problem. It appears that when I actually click on the submit button...everything seems to load properly.

It's when I click enter on the keyboard instead of the submit button with my mouse when the code error's out and the form data is not loaded.

any suggestions?

Could it be an issue of using the <label> tag around the submit button?

A quick fix...

<input type="submit" name="x" value="Submit" />
<input type="hidden" name="Submit" value="1" />

Thanks itenz - Your last post did the trick. I'm still a little confused as to why this would happen and why it is necessary to employ the work around you suggested. I suppose that I just need to do some additional research on my end.

Thanks again!!!

Only "activated" submit buttons will be submitted with the form; by simply pressing enter, no submit button is ever activated - the form is simply submitted.

An alternative fix might be to check if a specific field in the form was submitted, though this might not work well with dynamic forms (and thus the hidden INPUT element is an easy fix).

Also, don't forget to mark this thread resolved (if it is).
