[SOLVED] PHP Validation!

KashMoney · December 6, 2007

Hello,

I have some issues with my php validation form.

I need help with email field validation, Send the data to my email, and finally when submit have it say on the next page or even same page, Successfully sent.

<?
// Create an empty array to hold the error messages.
$arrErrors = array();
//Only validate if the Submit button was clicked.
if (!empty($_POST['Submit'])) {
    // Each time there?s an error, add an error message to the error array
    // using the field name as the key.
    if ($_POST['firstname']=='')
        $arrErrors['firstname'] = 'Please provide your first name.';
    if ($_POST['lastname']=='')
        $arrErrors['lastname'] = 'Please provide your last name.';
    if ($_POST['email']=='')
        $arrErrors['email'] = 'A valid email address is required.';
    if ($_POST['subject']=='')
        $arrErrors['subject'] = 'Please enter a subject.';
    if ($_POST['message']=='')
        $arrErrors['message'] = 'Please enter content in the message box.';
    if (count($arrErrors) == 0) {
        // If the error array is empty, there were no errors.
        // Insert form processing here.
    } else {
        // The error array had something in it. There was an error.
        // Start adding error text to an error string.
        $strError = '<div class="formerror"><p>Please check the following and try again:</p><ol>';
        // Get each error and add it to the error string 
        // as a list item.
        foreach ($arrErrors as $error) {
            $strError .= "<li>$error</li>";
        }
        $strError .= '</ol></div>';
    }
}
?>

you can try this for email validation

<?php
if (!preg_match('/^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i', $_POST['email'])) {
    echo 'Email entered is not valid';
} 
?>

I tried that and when i hit submit it doesn't display the email error!

blueman378 · December 6, 2007

i know it might seem stupid but come people do do it ::) but are you entering a invalid email?

KashMoney · December 6, 2007

I simply left something out of the php side now it works! My mistake. Now just need help sending the data to my email and when someone clicks submit it says successfully sent.

KashMoney · December 7, 2007

I am not trying to bump up my post but I did the part where when someone click submit it sents me an email but the thing is php doesn't do any validation when I leave something blank on the form field.

Here is the part that I did;


<?php

        if(isset($_POST['submit'])) 
	{
        
            $to = "myemail@name.com"; 
            $subject = "Submission Form";
            $fname_field = $_POST['firstname'];
            $lname_field = $_POST['lastname'];
            $email_field = $_POST['email'];
            $web_field = $_POST['web'];
            $subject_field = $_POST['subject'];
            $message = $_POST['message'];
                     
            $body = " First Name: $fname_field\n Last Name: $lname_field\n E-Mail Address: $email_field\n Website URL: $web_field\n Subject: $subject_field\n Message: $message\n";
        
            echo "<center>The message was sent successfully!</center>";
            mail($to, $subject, $body);
            
   	} 

else 
	{
        	echo "<center>Error Try Again!</center>";
        	}
        ?>

Any help would be appreciated!

Thanks,

KashMoney

You should do the validation stuff after the button is pressed i.e.

<?php

        if(isset($_POST['submit'])) 
	{
// do your validation here 
                  if (error) { display error }
                  else { continue with other code...  }


?>

revraz · December 7, 2007

PHP doesn't do validation unless you put the code in to do it.

PHP doesn't do validation unless you put the code in to do it.

See the first post, he has done it

Not sure what you mean on the code part?

~n[EO]n~ · December 7, 2007

see this... hope you get the idea

<?php
# after user presses submit button.....
if(isset($_POST['submit'])) 

{
        	// check for validation .... 
		if ($_POST['firstname']=='')
        	$arrErrors['firstname'] = 'Please provide your first name.';
   			if ($_POST['lastname']=='')
        	$arrErrors['lastname'] = 'Please provide your last name.';
		if (!preg_match('/^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i', $_POST['email'])) 
		$arrErrors['email'] = 'A valid email address is required.';
		if ($_POST['subject']=='')
        	$arrErrors['subject'] = 'Please enter a subject.';
    		if ($_POST['message']=='')
        	$arrErrors['message'] = 'Please enter content in the message box.';
		// till here you did the validation 

		# now check if error is empty or not, if empty do the mail 
		if (count($arrErrors) == 0) // same as your code.... if errors are 0 process mail... 
		{
		$to = "myemail@name.com"; 
            $subject = "Submission Form";
            $fname_field = $_POST['firstname'];
            $lname_field = $_POST['lastname'];
            $email_field = $_POST['email'];
            $web_field = $_POST['web'];
            $subject_field = $_POST['subject'];
            $message = $_POST['message'];
                     
            $body = " First Name: $fname_field\n Last Name: $lname_field\n E-Mail Address: $email_field\n Website URL: $web_field\n Subject: $subject_field\n Message: $message\n";
        
            echo "<center>The message was sent successfully!</center>";
            mail($to, $subject, $body);
		}
		else 
		{
		# there are some errors... display it 
		echo "ERRORS OCCURED...."; 
		}
            
} 

?>

The thing is though my validation doesn't display on exactly which form is missing like i had it before. It highlights it.

~n[EO]n~ · December 7, 2007

Try this now... php is case sensitive, so Submit and submit is different... you copy this all and see the changes...

<?php
$arrErrors = "";
# after user presses submit button.....
if(isset($_POST['submit'])) 

{
        	// check for validation .... 
		if ($_POST['firstname']=='')
        	$arrErrors= 'Please provide your first name.<BR>';
   			if ($_POST['lastname']=='')
        	$arrErrors.= 'Please provide your last name.<BR>';
		if (!preg_match('/^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i', $_POST['email'])) 
		$arrErrors.= 'A valid email address is required.<BR>';
		if ($_POST['subject']=='')
        	$arrErrors.= 'Please enter a subject.<BR>';
    		if ($_POST['message']=='')
        	$arrErrors.= 'Please enter content in the message box.<BR>';
		// till here you did the validation 

		# now check if error is empty or not, if empty do the mail 
		if (empty($arrErrors)) // same as your code.... if errors are 0 process mail... 
		{
		$to = "myemail@name.com"; 
            $subject = "Submission Form";
            $fname_field = $_POST['firstname'];
            $lname_field = $_POST['lastname'];
            $email_field = $_POST['email'];
            $web_field = $_POST['web'];
            $subject_field = $_POST['subject'];
            $message = $_POST['message'];
                     
            $body = " First Name: $fname_field\n Last Name: $lname_field\n E-Mail Address: $email_field\n Website URL: $web_field\n Subject: $subject_field\n Message: $message\n";
        
            echo "<center>The message was sent successfully!</center>";
            $sendmail = mail($to, $subject, $body);
		if (!$sendmail) { echo "Mail could not be sent";};
		}
		else 
		{
		# there are some errors... display it 
		echo "ERRORS OCCURED...."; 
		}
            
}

I see what you are trying to do, but I want it to go to another page with just the text saying sent successfully. When i do not put anything on the form I want it to highlight like a box in red then when you put something in then it goes away on submit. Not to be annoying. Not what I wanted done. I mean the idea of the stuff showing on top of the form of the missing stuff but the highlights are gone and the next page saying mail successfully gone is not in the code that you put out.

Please bare with me.

~n[EO]n~ · December 7, 2007

Please copy / paste this and check.... Did you mean like this.. To redirect to another page with your custom message, make that page and change the name of the file in header ("Location:mailsent.php");

<?php
$arrErrors = array();

		$arrErrors['email']= 'A valid email address is required.<BR>';
		if ($_POST['subject']=='')
        	$arrErrors['subject']= 'Please enter a subject.<BR>';
    		if ($_POST['message']=='')
        	$arrErrors['message']= 'Please enter content in the message box.<BR>';

		// till here you did the validation 


		$my_css1 = (empty($_POST['firstname'])) ? 'input_err' : 'input_normal';
