Simple form validate
Friday, January 9th, 2009Salam,
Ini adalah simple fom validate aku buat sendirik. So sesapa nak try buleh copy dan paste jer.
function-function yang terlibat :
//pastikan email adalah valid
function valid_email($address){
if(ereg("^[a-zA-Z0-9_]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$", $address)){
//return true;
} else {
echo '<script type="text/JavaScript">';
echo 'alert(\'Please key-in valid email address\')';
echo '</script>';
echo '<script type="text/JavaScript">';
echo 'history.go(-1)';
echo '</script>';
exit();
}
}
//pastikan upload adalah valid
function valid_upload($fail,$field){
$tmpfail = $_FILES[$field]['tmp_name'];
if(is_uploaded_file($tmpfail)){
//return true;
} else {
echo '<script type="text/JavaScript">';
echo 'alert(\'No file selected fo upload\')';
echo '</script>';
echo '<script type="text/JavaScript">';
echo 'history.go(-1)';
echo '</script>';
exit();
}
}
//pastikan field tidak kosong
function not_empty_field($field){
foreach($field as $key => $value){
$value = trim($value);
if(!empty($value)){
$err_msg[n] .= $value;
//return true;//ada data
} else {
$err_msg[y] .= 'Field ['.$key.'] cannot empty\n';
//return false;//field kosong
}
}
return $err_msg;
}
//back jika field tidak valid
function go_back($search_array){
if (array_key_exists('y', $search_array)) {
echo '<script type="text/JavaScript">';
echo 'alert(\''.$search_array['y'].'\')';
echo '</script>';
echo '<script type="text/JavaScript">';
echo 'history.go(-1)';
echo '</script>';
exit();
} else {
//echo 'form valid';
}
}
Dan macam mana nak guna dan panggil function :
$get_value = array(
'textfiel'=>$_POST['textfield_name1'],
'Field of Study'=>$_POST['textfield_name2'],
'Topic of Research'=>$_POST['textfield_name2']
);
}
//form validate
go_back(not_empty_field($get_value));
