I made a neat little PHP function today which does error message handling, and I figured I'd share:
<?php
function check_posts() {
$found = array();
foreach ($_POST as $x => $y) {
$conditions = array("first" => (strlen($y) < 5), "last" => (strlen($y) < 2),
"email" => (!filter_var($y, FILTER_VALIDATE_EMAIL)), "password" => (strlen($y) < 5),
"password_check" => ($_POST["password_check"] != $_POST["password"]));
$errors = array(
"first" => "fname less then 5 ", "last" => "last name less then 2", "email" => "invalid email",
"password" => "pass less than 5", "password_check" => "second pass didnt match first");
if ($conditions[$x]) $found[] = $errors[$x];
}
$i = 1; if (count($found) > 0) {
foreach ($found as $z) { echo "<p>$i. $z</p>"; $i++; }
} else {
echo "passed validation.";
//validation code
}
}
?>
The red area contains the conditional statement which you would want to validate, ie: empty($country), or something. If it returns true then you have an error.
The blue area defines the corresponding messages.
These two areas are organized by post names (easiest way I thought).
After some thought I also decided to share the initial testing code:
<?php
function check_posts() {
$found = array();
foreach ($_POST as $x => $y) {
if ($x == "check") break;
$conditions = array("first" => (strlen($y) < 5), "last" => (strlen($y) < 2),
"email" => (!filter_var($y, FILTER_VALIDATE_EMAIL)), "password" => (strlen($y) < 5),
"password_check" => ($_POST["password_check"] != $_POST["password"]));
$errors = array(
"first" => "fname less then 5 ", "last" => "last name less then 2", "email" => "invalid email",
"password" => "pass less than 5", "password_check" => "second pass didnt match first");
if ($conditions[$x]) $found[] = $errors[$x];
}
$i = 1; if (count($found) > 0) {
foreach ($found as $z) { echo "<p>$i. $z</p>"; $i++; }
} else {
echo "passed validation.";
//validation code
}
}
