JavaScript vs PHP validation problem

ronanmccoy

I am using Javascript to validate a form. I am using a querytstring and PHP to make the page call itself and process the form data. The problem is, if javascript validates the info and presents an alert box telling the user a field is missing, then clicking on the ok button submits the form!! So no matter whether the form is complete or not, it is still submitted and processed. How do i stop this from happening??? How do i keep the field from processing when there is a missing field? I was using a javascript code snippet in like this:
IF(error){
alert("the form is not complete");
return false;
}else{
return true;
}

The PHP form simple says:
<FORM Action="<?php PHP_SELF?>?do=process" method="post" onsubmit.....>

Any help would be greatly appreciated.

Try switching your return true and return false statements.

You left out the most important piece; how you call the validation function with the onsubmit event.

Make sure you are calling it with the return operator like this:

onSubmit=\"Javascript: return validateForm(this)\"

Another option you might try is to replace the "return true" line with "submit()". This will make it such that if all fields are filled out correctly, the form will be submitted, and if the fields are not filled out properly, the form will not be sent.

It will submit, anyway, if the function returns TRUE.

I tried swapping the "return true" and the "return false" and also using an "submit()" call in the if statements where the "return true" would be. Still it keeps submitting the form.
I finally decided to use two pages to get the job done. The first page is a regular HTML page that holds the form and has the javascript validation. The second page is the php page that does the processing that I need. This seems to have solved the problem of php and javascript working together. It's not the ideal setup I want, but it'll do for now. Thanks for the ideas all, and if i do finally figure it all i'll post it here. on to the next problem...!
