eregi help

[fantomel]

hello since php 5.3 eregi is deprecated can you please advice me what function should i use instead and give an example ? thank you very much

Use preg_match. Do note that preg_* based functions require you to use regex.

ok i understand

[.josh]

also note that the preg_x functions uses the pcre engine (perl compatible regular expressions) instead of the posix engine used by ereg_x functions, so there are some syntax and behavioral differences.

i`m back i have made the changes in the code where i needed but i need some experts who used before preg_match since it's my first time.. and i would to know if it's correct.

 

<?php

if (isset($_POST['submit'])) {
    if (empty($_POST['username'])) {
        $errors[] = 'Empty Username.';
    }
    if (strlen($_POST['username']) < 4) {
        $errors[] = 'Username too short.';
    }
    if (strlen($_POST['username']) > 10) {
        $errors[] = 'Username too long.';
    }
    if (!preg_match('^[a-zA-Z0-9]*$', $_POST['username'])) {
        $errors[] = 'Username Contains Invalid Characters.';
    }

    if (empty($_POST['password'])) {
        $errors[] = 'Empty Password';
    }
    if (strlen($_POST['password']) < 6) {
        $errors[] = 'Password too short';
    }
    if (!preg_match('^[a-zA-Z0-9]*$', $_POST['username'])) {
        $errors[] = 'Password Contains Invalid Characters.';
    }
    if (empty($_POST['name']) || !preg_match('^[a-zA-Z0-9]*$', $_POST['name'])) {
        $errors[] = 'Name is empty or incorect.';

        $_POST['email'])) {
        $errors[] = 'E-mail is empty or incorect.';
    }
    if (empty($_POST['zipcode']) || !preg_match('^[0-9]*$', $_POST['zipcode'])) {
        $errors[] = 'Zip Code is empty or incorect.';

        $errors[] = 'Phone is empty or incorect.';

$username = $_POST['username'];
$sql = "SELECT * FROM `tbl_users` WHERE `username_users` = '$username' ";
$result = mysql_query($sql);

You need to start your regex patterns with delimiters first, eg ~your pattern here~

 

So the following pattern ^[a-zA-Z0-9]*$ can be rewritten as ~([A-Z0-9]+)~i

 

I would recommend you to have read of this regex tutorial for the basics on regular expressions. Also check out regular-expressions.info too.

Side note. My last name contains a -, you should allow them them in your sir names.
