Accessing Form Variables

Anon

I needed to know how do I access the variables of the form when the form calls itself - <form name=myForm method=post action="<?php echo $PHP_SELF ?>"> if the input type is not "SUBMIT", but it is "BUTTON"?

To explain myself a little more clearly, here is the code:

<?php
if( $btnSave ) {
echo ("Save Clicked!");
}
else {
echo ("Save not clicked!");
}
?>

<head>
<script>
function validateForm()
{
if (document.myForm.myText == "" )
{
alert("Error in myText");
document.myForm.myText.focus();
}
else
{
document.myForm.submit();
}
}
</script>
</head>
<body>
<form name=myForm method="post" action="<?php echo $PHP_SELF ?>">
<input type="text" name="myText"><br>
<input type="button" name="btnSave" value="SAVE" onclick="validateForm();">
</form>
</body>

I am getting "Save not clicked" even if I have clicked on the SAVE button.

Please advise as to how should I deal with this problem.

Thank you...

It seems to me that it would be more appropriate for you to use a "submit" button and use php to validate your form. ie
<?php
if( $submit ) {
if ($myText == "") {
print "Save Clicked";
}
else {
print "Save not clicked";
}

I understand the alternative you have suggested. However, the example I had given was a generic and simple one. What I need to know is whether I can do some client-side validations first before calling the submit function of the form instead of making it of type "SUBMIT".

In ASP, whether I have the button as type BUTTON or SUBMIT, I can access the variables by Request.Form() function. In PHP it seems that I can access the variables ONLY if the input is of type SUBMIT and not BUTTON.

Is this correct?

What if the client has javascript turned off, I think it is better to do your validation on the server side.
