Form validation with 2 actions if error or not

[Eggzorcist]

I'm wondering wether it's possible that if there is an error as in if $error isset, it will stay on this page displaying the error otherwise, it will go to the destined action='register.php' is this possible?

 

if so, how would i be doing this?

 

Thanks a bunch!

on your place onSubmit("return action();") on your <form>

and make a function named action() or any thing you want to name it dn make a if else condition for your validation if validation creates an error return false; and if no errors return true;

[Eggzorcist]

so on the register button, the onclick? I'm not sure if I understand this technique...

[Eggzorcist]

So you mean if I create a onSubmit, the onSubmit function will pass before the action? meaning if Onsubmit = false it wont submit? and if its true, it full go to the action?

[merck_delmoro]

yup

place onSubmit("return action();") on your <form>

and make a function named action() or any thing you want to name it dn make a if else condition for your validation if validation creates an error return false; and if no errors return true;

Though it seems like the function has to be in javascript, it only works when it is. I tried with a php function but nothing worked.

Sorry I forgot to tell you that ^^

 

yup the function was a JavaScript function

Well, is there a way to create a regex style validation? So basically if I already have

 

 if (!preg_match("/\A[^0-9][a-zA-Z0-9_]+([.][a-zA-Z0-9_]+)*[@][a-zA-Z0-9_]+([.][a-zA-Z0-9_]+)*[.][a-zA-Z]{2,4}$/", $email)){
	$Error .= "Email Address Must Be In format: [username]@[domain].[extension] <br />";
}

 

is there a javascript way of doing this? My javascript is pretty bad

what are you try to validate mate, what email what?

[Eggzorcist]

I'm trying to validate, firstly, a name more than 3 letters. and an email.

 

 

[redarrow]

do u understand this mate look

<?php

$name="redarrow";

if(preg_match("/^[a-z]{3}$/",$name)){

echo "correct name is 3 letters long";

exit;

}else{

echo "no the name was more then 3 letters long";

exit;
}


?>

[Eggzorcist]

Yes, I do. However, this needs to be in javascript to be able to use the onSubmit html function, because I'm trying to use the validation before the action which leads off to another file. Is there a way to implement the php regex prior the action(register.php) file?

 

 

Thanks

I think you were asking for something like this. Submit the form to the same page then:

<?php
if (isset($error) {
    echo "Error Found: $error";
} else {
    header('Location: register.php');
}
// ... redo form
?>
