<?php 
if ($_POST){
$error = "";
if($_POST['a1']  == ""){
$error ="nr1 FALSE<br />";
}
if($_POST['a2'] == ""){
$error ="nr2 FALSE<br />";
}
if($_POST['a3'] == ""){
$error ="nr3 FALSE<br />";
}
if ($error != ""){
echo "$error";
}else {
echo $_POST['a1'];
echo $_POST['a2'];
echo $_POST['a3'];
}
}else{
?>
<form method="POST" action="/index.php">
a1<input type="text" name="a1" /><br />
a2<input type="text" name="a2" /><br />
a3<input type="text" name="a3" /><br />
<input type="submit" name="submit" />
</form>
<?php } ?>

Velos lai $error izdruka visas kludas, nevis tikai vienu!

Pemeram ja netiek aizpildiits a1 un a2. Gribu lao mainigais $error izdruka kludu par abiem.

Ka to panakt, nepieskirot katrai kludas izdrukai savu mainigo!?

Virknes beigās liek katru jaunu kļūdu:

$errors = '';
$errors .= 'abc';
$errors .= '123';
echo $errors;  // abc123

Kļūdas liek masīvā:

$errors = array();
$errors[] = 'abc';
$errors[] = '123'; // array('abc', '123')
foreach($errors as $error) {
  echo $error;
}

 

Ja lietosi <br /> tad liec virknē, ja gribi izvadīt kā sarakstu <ul><li></li></ul> vai ko vairāk ar tām kļūdām darīt, vari lietot masīvu.
