Menü Templates Teil 3 (CMS)
Diese If-Abfrage werden wir bei den anlegen einer neuen Seite bentzen. Hier wird je nach dem ob das Formular bereits abgesendet wurde oder nicht ein anderer Block eingeblendet. /system/templates/menu_new.html:
<h1>{LANG:NEW_MENU}</h1> {IF:NOTSUCCEEDED} <form action="{VAR:URL}" method="POST"> {LANG:NAME}: <input name="name"><br /> <input type="submit" value="{LANG:CREATE}" /> </form> {/IF:NOTSUCCEEDED} {IF:SUCCEEDED} <p>{LANG:MENU_CREATED}</p> <form action="{VAR:EDITURL}" method="POST"> <input type="submit" value="{LANG:ADD_ENTRIES}" /> </form> {/IF:SUCCEEDED}
Dieses Template wird dann von der /admin/includes/menue-new.php gefüllt:
<?PHP $template = new Template(); $template->load("menu_new","../"); $template->show_if("NOTSUCCEEDED",!$_POST['name']); $template->assign_var("URL","/admin/index.php?page=menue-new"); if($_POST['name']){ $template->show_if("SUCCEEDED"); $id = Menu::create($GLOBALS['db']->EscapeString($_POST['name'])); if($id){ $template->assign_var("EDITURL","/admin/index.php?page=menu-edit&menu=".$id); } else{ $template->load("message","../"); $template->assign_var("MESSAGE",$language->getString("MENU_NOT_CREATED")); } } $template->output(); ?>
Das Bearbeiten des Menüs ist etwas schwieriger. Hierfür müssen auch noch die Klassen Menu und MenuEntry bearbeitet werden. Fangen wir an mit der /system/classes/menuentry.php. Diese bekommt die neue Funktion getEditableCode. Die Funktion displayEditAbleCode ruft diese einfach nur auf und gibt sie aus:
public function getEditableCode(){ $template = new Template(); $template->load("menuentry_editable","../"); $template->assign_var("ID", $this->id); $template->assign_var("TITLE",$this->title); if($this->type == 0){ $template->assign_var("SELECTEDINTERNAL"," selected="1""); $selector = new PageSelector(); $selector->name = $this->id.'_href'; $selector->value = $this->href; $template->assign_var("VALUECONTROL",$selector->getCode()); } else{ $template->assign_var("SELECTEDINTERNAL",""); if($this->type == 1){ $template->assign_var("SELECTEDIEXTERNAL"," selected="1""); $template->assign_var("VALUECONTROL","<input name="".$this->id."_href" value="".$this->href."" />"); } else{ $template->assign_var("SELECTEDIEXTERNAL",""); if($this->type == 2){ $template->assign_var("SELECTEDSUBMENU"," selected="1""); $selector = new MenueSelector(); $selector->name = $this->id.'_href'; $selector->value = $this->href; $template->assign_var("VALUECONTROL",$selector->getCode()); } } } return $template->getCode(); } public function displayEditAble(){ echo $this->getEdiableCode(); }
Diese Funktion benutzt das neue Template /system/templates/menuentry_editable.html:
<input name="{VAR:ID}_title" value="{VAR:TITLE}" /> <select name="{VAR:ID}_type" onChange="typeSelected()"> <option value="0"{VAR:SELECTEDINTERNAL}>{LANG:PAGE_INTERNAL}</option> <option value="1"{VAR:SELECTEDIEXTERNAL}>{LANG:PAGE_EXTERNAL}</option> <option value="2"{VAR:SELECTEDSUBMENU}>{LANG:MENU}</option> </select> {VAR:VALUECONTROL} <input type="submit" name="{VAR:ID}_delete" value="X" /><br />
In der neuen Funktion getEtidableCode der /system/classes/menu.php wird nun der Code aller Menüeinträge zusammengefasst und weitergegeben:
function getEditableCode($id){ $res = ""; $entries = self::getEntries($id); if($entries){ foreach($entries as $entry){ $res .= $entry->getEditableCode(); } } return $res; } function displayEditable($id){ echo $this->getEdiableCode($id); }
Jetzt kommen wir zur richtigen Menü-Bearbeiten Seite. Zuerst das Template /system/templates/menu_edit.html:
<h1>{LANG:EDIT_MENU}</h1> <p>{VAR:MESSAGE}</p> <form action="{VAR:URL}" method="POST"> <h2>{LANG:EDITMENU}</h2> {VAR:EDITABLEMENU} <input name="save" type="submit" value="{LANG:SAVE}"/> <h2>{LANG:ENTRY_ADD}</h2> <table> <tr> <td style="width:100px;">{LANG:TEXT}:</td> <td><input name="newtitle" style="width:200px;" /></td> </tr> <tr> <td>{LANG:TYPE}:</td> <td> <script language="javascript"> function typeSelected(){ document.getElementsByName('newPage')[0].style.visibility ='hidden'; document.getElementsByName('newurl')[0].style.visibility ='hidden'; document.getElementsByName('newMenu')[0].style.visibility ='hidden'; if(document.getElementById('type').selectedIndex == 0){ document.getElementsByName('newPage')[0].style.visibility ='visible'; document.getElementById('newLabel').innerHTML = '{LANG:PAGE}:'; } else if(document.getElementById('type').selectedIndex == 1){ document.getElementsByName('newurl')[0].style.visibility ='visible'; document.getElementById('newLabel').innerHTML = 'Url:'; } else{ document.getElementsByName('newMenu')[0].style.visibility ='visible'; document.getElementById('newLabel').innerHTML = '{LANG:MENU}:'; } } </script> <select id="type" name="type" onChange="typeSelected()" style="width:200px;"> <option value="0">{LANG:PAGE_INTERNAL}</option> <option value="1">{LANG:PAGE_EXTERNAL}</option> <option value="2">{LANG:MENU}</option> </select> </td> </tr> <tr> <td><span id="newLabel">{LANG:PAGE}</a>:</td> <td> <input name="newurl" value="http://" style="width:200px;visibility:hidden" /> {VAR:MENUSELECTOR} {VAR:PAGESELECTOR} </td> </tr> </table> <input name="add" type="submit" value="Hinzufügen"/> </form>
Der dazugehörige Code der /admin/includes/menu-edit.php sieht so aus:
<?PHP $template = new Template(); $template->load("menu_edit","../"); if($_POST['add']){ if(trim($_POST['newtitle']) != ""){ if(trim($_POST['newurl']) != ""){ $entry = new MenuEntry(); $entry->menu = $_GET['menu']; $entry->title = $_POST['newtitle']; $entry->type = $_POST['type']; if($entry->type == 0){ $entry->href = $_POST['newPage']; } else if($entry->type == 1){ $entry->href = $_POST['newurl']; } else{ $entry->href = $_POST['newMenu']; } $res = $entry->save(); if($res){ $template->assign_var("MESSAGE",$GLOBALS['language']->getString("ENTRY_ADDED")); } else{ $template->assign_var("MESSAGE",$GLOBALS['language']->getString("ENTRY_NOT_ADDED")); } } else{ $template->assign_var("MESSAGE",$GLOBALS['language']->getString("ENTER_LINK_TARGET")); } } else{ $template->assign_var("MESSAGE",$GLOBALS['language']->getString("ENTER_LINK_TITLE")); } } else if($_POST['save']){ foreach($_POST as $param=>$value){ if(strlen($param) >= 6){ if(substr($param,-5,5) == "_href"){ $entries[substr($param,0,-5)][href] = $value; } else if(strlen($param) >= 7 && substr($param,-6,6) == "_title"){ $entries[substr($param,0,-6)][title] = $value; } else if(substr($param,-5,5) == "_type"){ $entries[substr($param,0,-5)][type] = $value; } } } foreach($entries as $id=>$params){ $entry = new MenuEntry(); $entry->id = $id; $entry->menu = $_GET['menu']; $entry->title = $params['title']; $entry->href = $params['href']; $entry->type = $params['type']; $entry->save(); } } else{ foreach($_POST as $param=>$value){ if(strlen($param) >= 8){ if(substr($param,-7,7) == "_delete"){ Menu::deleteEntry($GLOBALS['db']->EscapeString($_GET['menu']), $GLOBALS['db']->EscapeString(substr($param,0,-7))); } } } } $template->assign_var("URL","index.php?page=menu-edit&menu=".urlencode($_GET['menu'])); $template->assign_var("EDITABLEMENU",Menu::getEditableCode($GLOBALS['db']->EscapeString($_GET['menu']))); $selector = new MenueSelector(); $selector->name = 'newMenu'; $selector->value = -1; $selector->style = 'width:200px;position:relative;left:-210px;visibility:hidden'; $template->assign_var("MENUSELECTOR", $selector->getCode()); $selector = new PageSelector(); $selector->name = 'newPage'; $selector->value = -1; $selector->style = 'width:200px;position:relative;left:-415px;'; $template->assign_var("PAGESELECTOR", $selector->getCode()); $template->assign_var("MESSAGE",""); $template->output(); ?>
Das Löschen eines Menüs ist wieder etwas leichter. Hierfür gibt es das neue Template /system/templates/menu_delete.html:
<p>{LANG:DELETE_MENU_ASK}</p> <a href="{VAR:CANCELURL}">{LANG:CANCEL}</a> <a href="{VAR:DELETEURL}">{LANG:DELETE_MENU}</a>
Die Steuerung erfolgt in der /admin/includes/menu-delete.php:
<h1><?PHP echo $language->getString("DELETE_MENU"); ?></h1> <?PHP $template = new Template(); if(!$_GET['delete']){ $template->load("menu_delete","../"); $template->assign_var("CANCELURL","/admin/?page=menues"); $template->assign_var("DELETEURL","/admin/?page=menu-delete&menu=".$_GET['menu']."&delete=true"); } else{ $template->load("message","../"); if(Menu::delete($GLOBALS['db']->EscapeString($_GET['menu']))){ $template->assign_var("MESSAGE",$language->getString("MENU_DELETED")); } else{ $template->assign_var("MESSAGE",$language->getString("MENU_NOT_DELETED")); } } $template->output(); ?>
Für die Templates braucht ihr die neue Sprachdatei. Jetzt sind wir mit den Templates der Menüs soweit durch. Als nächstes kommt das Dateisystem an die Reihe.
