Stopping submit when PHP creates form...

Anon

I want to stop the Submit function when a form field has not been entered. However, the problem is that the form field is created by PHP code.

This is what I have

while ($row = mysql_fetch_array($result))
{
$vard - $row['vard'];

$opt .= "<option value=\"$vard\">$vard</option>";
}

This gets all the possible values and puts them into the option box

<option selected>choose</option>
<? echo "$opt"; ?>

This makes the selected option in the box equal to "choose"

So if I write a JavaScript:

<SCRIPT LANGUAGE="JavaScript">
function dutch(form)
{

  if (form1.box.value = "choose"){
  alert('You must choose!');
     return false
     }
     }

shouldn't that stop the submit?

This is the <form> code:
<form method="post" action=something.php name="form1" onSubmit=dutch(this)>

Does any of this make sense? Why doesn't it work - I have tried many things such as:

<form method="post" action=something.php name="form1" <? If ($vard = "choose") echo 'onSubmit=dutch(this)' ?> > etc.

The problem is that this does not stop the submit - the alert works but the submit goes through when I click OK no matter what I do.

I dont do much javascipt but maybe you could put in a php \' if \' statement like the one in the sample script below and adjust it to your script. Test it out.

Let me know if this is of any help!

<body>

<?php

if ($submit) {

if (!$first || !$last) {



$error = \"Sorry! You didn\'t fill in all the fields!\";

} else {
	// process form
                          echo \"Thank You!\";

}

}

if (!$submit || $error) {

echo $error;

<P>

FIELD 1: <input type=\"text\" name=\"first\" value=\"<?php echo $first ?>\"><br>

FIELD 2: <input type=\"text\" name=\"last\" value=\"<?php echo $last ?>\"><br>

</form>

<?php

} // end if

?>
<br>
<em>This script checks to see if any fields are empty</em>
</body>

Not that lesson, this lesson....

It is simple, really. If you want a return value in JavaScript, you put onSubmit="return dutch(form)" - that way the value is returned from the function. Not the way I am used to doing it in other languages, but in every example I looked at, there it was - since the onSubmit was working, I didn't look that closely at it (that's my story, and I'm sticking to it!)
