Find String and append another string after it

Question

I have a page with following code:

'customCode' => 'input name="last_name" id="last_name" size="25" maxlength="25" type="text" value="{$fields.last_name.value}"'

I want to run a script that will add onblur="name_valid(this.value);" after name="last_name"

Resulting Output should be like

'customCode' => 'input name="last_name" onblur="name_valid(this.value);" id="last_name" size="25" maxlength="25" type="text" value="{$fields.last_name.value}"

1. What have you tried? 2. I assume adding onblur=... at the end of string doesn't change anything. — u_mulder

How about this,

$string = 'input name="last_name" id="last_name" size="25" maxlength="25" type="text" value="{$fields.last_name.value}"';

echo $string = str_replace('name="last_name"', 'name="last_name" onblur="name_valid(this.value);" ', $string);

A simple string replace will do it.

<?php 
$input_str = '<input name="last_name" id="last_name" size="25" maxlength="25" type="text" value="{$fields.last_name.value}>'; 
$new_str= str_replace('name="last_name" ','name="last_name" onblur="name_valid(this.value);" ',$input_str);
echo $new_str; 
?>
