PHP automatically generated form code sharing

During PHP development, we sometimes encounter forms that are not fixed and need to be dynamically generated during the program running. here we will share a class for PHP to automatically create forms for everyone. php.

<? Php // Form. phpclass form {var $ layout = true; // whether to use table layout var $ action; // URL var $ method to be submitted to the form; var $ enctype = ""; var $ name = ""; var $ id = ""; var $ class = ""; function form ($ action, $ method = "POST ") {// initialize the member variable $ this-> action = $ action; $ this-> method = $ method;} function form_start () through the constructor () {$ text = "\ n";} else {$ text ="\ N ";}return $ text ;}// function of the text box function form_text ($ name, $ id, $ label_name, $ label_for, $ value =" ") {$ text ="Form_label ($ label_name, $ label_for); $ form_item = $ this-> form_item ($ label, $ text); return $ form_item ;} // function form_passwd ($ name, $ id, $ label_name, $ label_for, $ value = "") {$ text ="Form_label ($ label_name, $ label_for); $ form_item = $ this-> form_item ($ label, $ text); return $ form_item ;} // hide the domain function form_hidden ($ name, $ id, $ label_name, $ label_for, $ value = "") {$ text ="Form_label ($ label_name, $ label_for); $ form_item = $ this-> form_item ($ label, $ text); return $ form_item ;} // file domain function form_file ($ name, $ id, $ label_name, $ label_for, $ size = "") {$ text ="Form_label ($ label_name, $ label_for); $ form_item = $ this-> form_item ($ label, $ text); return $ form_item;} // check box function form_checkbox ($ name, $ label = array (), $ label_name, $ label_for = "") {$ I = 0; $ text = array (); foreach ($ label as $ id => $ value) {$ text [$ I] =""; $ Text [$ I]. ="{$ Value}"; $ I ++;} $ label = $ this-> form_label ($ label_name, $ label_for); $ form_item = $ this-> form_item ($ label, $ text ); return $ form_item;} // function form_radio ($ name, $ label = array (), $ label_name, $ label_for = "") {$ I = 0; $ text = array (); foreach ($ label as $ id => $ value) {$ text [$ I] =""; $ Text [$ I]. ="{$ Value}"; $ I ++;} $ label = $ this-> form_label ($ label_name, $ label_for); $ form_item = $ this-> form_item ($ label, $ text ); return $ form_item;} // the drop-down menu function form_select ($ id, $ name, $ options = array (), $ selected = false, $ label_name, $ label_for, $ onchange = "") {if ($ onchange! = "") {$ Text ="\ N ";}else {$ text ="\ N ";} foreach ($ options as $ value => $ key) {if ($ selected = $ value) {$ text. =" \ t{$ Key}\ N ";} elseif ($ selected = false) {$ text. =" \ t{$ Key}\ N ";}}$ text. =""; $ Label = $ this-> form_label ($ label_name, $ label_for); $ form_item = $ this-> form_item ($ label, $ text); return $ form_item ;} // function form_selectmul ($ id, $ name, $ size, $ options = array (), $ label_name, $ label_for) {$ text ="\ N "; foreach ($ options as $ value => $ key) {$ text. =" \ t{$ Key}\ N ";}$ text. ="\ N "; $ label = $ this-> form_label ($ label_name, $ label_for); $ form_item = $ this-> form_item ($ label, $ text ); return $ form_item;} // button function form_button ($ id, $ name, $ type, $ value, $ onclick = "") {$ text ="Layout = true) {$ form_item ="\ N \ t {$ Text}\ N\ N ";}else {$ form_item = $ text;} return $ form_item;} // function of the text domain function form_textarea ($ id, $ name, $ cols, $ rows, $ label_name, $ label_for, $ value = "") {$ text ="{$ Value}\ N "; $ label = $ this-> form_label ($ label_name, $ label_for); $ form_item = $ this-> form_item ($ label, $ text ); return $ form_item;} // The function form_label ($ text, $ for) {if ($! = "") {$ Label ="{$ Text }:";} Else {$ label = $ text. ":";} return $ label;} function form_item ($ form_label, $ form_text) {switch ($ this-> layout) {case true: $ text ="\ N "; $ text. =" \ t"; $ Text. = $ form_label; $ text. ="\ N "; $ text. =" \ t"; $ Text. = $ form_text; $ text. ="\ N "; $ text. ="\ N "; break; case false: $ text = $ form_label; $ text. = $ form_text; break;} return $ text;} function CreateForm ($ form_item = array () {echo $ this-> form_start (); foreach ($ form_item as $ item) {echo $ item;} echo $ this-> form_end () ;}}?>

Example:

    
     
     User logon<? Phprequire_once ("form. php "); $ form = new form ($ _ SERVER ['php _ SELF ']); // submit to this page $ form-> layout = false; // no table layout is used. you can comment out this sentence to see how the result is different. $ name = $ form-> form_text ("userid", "userid", "username ", "userid"); $ passwd = $ form-> form_passwd ("passwd", "passwd", "password", "passwd "); $ submit = $ form-> form_button ("", "submit", "submit", "logon"); $ form_item = array ($ name, $ passwd, $ submit ); $ form-> CreateForm ($ form_item);?>
