Form Gen.

Ein wahnsinns praktisches Teil wenn mal schnell ein Formular benötigt das auch noch gleich mit validiert werden soll.

Script:

<?php class form_o_mat { var $id; //Form name (to identify if it was send) var $action; //Where should this form post? (if nothing, it self) var $caption; //Caption to show the user var $target = "_self"; //What should the target be? var $style; //If there is a css class for this form, put the name here var $enctype; //Will automaticly be set to multipart/form-data if there is a form with a file obj. var $hide = FALSE; //Shuld the form be hidden if there are no errors in the send data? var $_error=""; //Intern error trigger var $_error_msg=""; //Intern error message to be displayed var $_data=""; //Intern usage for storing the form data function insert_object( $name, $caption, $needed=FALSE, $type="text", $size="", $value="" ) { $needed_signal = ""; if( isset( $_POST[$this->id] ) ) { $this->_check_data( $name, $type, $needed ); $value = $_POST[$name]; } if( $needed == TRUE ) { $needed_signal = "* "; } $return = '<tr><td valign="top"><b>'. $caption .'</b>'. $needed_signal .'</td><td valign="top">'; $value = htmlspecialchars( $value ); switch( $type ) { case 'password': $size = preg_replace( "/\D/i", "", $size ); if( !empty( $size ) ) { $size = 'size="'. $size .'"'; } $attribs = 'type="password" '. $size; if( !empty( $value ) ) { $value = 'value="'. $value .'"'; } $return .= '<input name="'. $name .'"
