PHP FORM | w/immediate field validation

 

 

Hi

 

I am trying to complete a form with an error report in case a sender forgot to complete a name field or any other fields.  I was hoping to have an error

 

post immediately after the submit button is pushed.  But I do not want to redirect to an error page. Just to have a red colored error description appear

 

above the field.  What happens? After the submit button is pushed, page changes and gives out an error on line 42.  Which is where the line   

 

if{$error=="")  starts. Please help!  After four days of trying I give up.  I need help. I cant take this anymore!  I striped all the styling for quick

 

appearance here.

change

if{$error==""){
else{
   echo"<div align='center'>".$error."</div>";
}

 

to

if(!empty($error)) // NOTE THE ( at the start not {
{
   echo"<div align='center'>".$error."</div>";
   exit; // don't continue
}

Thank you, It worked I guess if I want to have msg come up next to the field I need to find a javascript since I want to validate on client side.  There is no way to post errors next to the field using .php?

[MadTechie]

Well you could echo them

ie

<label>Contact`s Name:</label><input name="name" type="text" value="" style="width: 35%;" > <?php if(empty($_POST['name'])) echo "Please enter a neme";  ?><br>

 

But client side validation works well

[haku]

Client side validation is good as an extra, but you should have server-side (php) validation as the default. People can turn off javascript (and some of us have it off by default), so if you don't validate server side as well as client side, then sometimes input won't be validated.

If you're wanting something instant, than use javascript. Otherwise, you can do it with PHP, with something like:

<?php
if(isset($_POST)) {
   // form validation
   // set any errors here.
   if(!isset($error)) {
      // submit form (or email it)
   }
}
if(!isset($_POST) || isset($error)) {
   // if form hasn't been submitted, or there was an error
   if(isset($error)) 
      echo $error.'<br />';
   ?>
   FORM HERE
   <?php
}
?>

 

Like haku said, if you did the javascript approach, make sure to do server side validation. Client side may be convenient, but not secure.

Thank you guys, for your time.  Good stuff,, I will try php and javascript to see what is batter for me.  I tried other forums this one is the best!

There is no better between PHP and Javascript, they do different things.

 

But when it comes to form validation, php is necessary, javascript just makes it look nicer.
