Check if String Contains a Number

[oliverj777]

Hello,

 

I'm working on an error form, and I want to check if the user inserted a number into the name field, and if so return an error.

 

I thought this might of worked, but it doesn't:

 

if(is_int($_POST['name'])){
     $arrErrors['name'] = 'Invalid name, remove numbers.';
}

 

Many thanks

This can do that

 

<?php
$text=$_POST['name'];
if (ereg('[^0-9]', $text)) {
	$arrErrors['name'] = "Invalid name, remove numbers.";
}
?>

ereg was deprecated as of php version 5.3, might be better off using preg_match instead

I hadn't checked that thanks, here is a preg_match version

 

<?php
$text=$_POST['name'];
if (preg_match('#[\d]#', $text)) {
	$arrErrors['name'] = "Invalid name, remove numbers.";
}
?>
