DIEVOLUTION TV + Blog

Immer wieder Sonntags: Leere. Der einzige wirklich freie Tag der Woche, das Blog ist leer, der Kopf ist leer, und irgendwie fällt mir kein Thema ein, was euch interessieren könnte. Daher gibts heute etwas ganz einfach, nämlich eine kleine Guestbook Anwendung mit CakePHP.

Dieses Guestbook könnt ihr wenn ihr möchtet verwenden – ein Link zum Cakeblog ist natürlich gern gesehen

Features:

• Einfache Installation
• Captcha Prüfung

Benötigt werden zudem folgende Komponenten:

• Pagination
• Captcha
• Meine Deutsch-Helperclass

Weiter nach dem weiterlesen

Zuerst die dafür nötige SQL Tabelle:


CREATE TABLE `guestbook_entries` (
`id` int(10) unsigned NOT NULL auto_increment,
`user_id` int(10) unsigned NOT NULL default '0',
`author` varchar(255) default NULL,
`entry` text,
`created` datetime default NULL,
`modified` datetime default NULL,
PRIMARY KEY (`id`)
)


Die Modeldatei guestbook_entry.php

<?php
class GuestbookEntry extends AppModel {
var $name = 'GuestbookEntry';
var $validate = array(
'name' => VALID_NOT_EMPTY,
'content' => VALID_NOT_EMPTY
);
}
?>

Die Controllerdatei guestbook_entries_controller.php


<?php
class GuestbookEntriesController extends AppController {
var $name = 'GuestbookEntries';
var $helpers = array('Html', 'Form', 'Deutsch', 'Pagination');
var $components = array('Captcha', 'Pagination');
function index() {
$criteria=NULL;
list($order,$limit,$page) = $this->Pagination->init($criteria);
$this->set('guestbookEntries', $this->GuestbookEntry->findAll($criteria,NULL,"GuestbookEntry.created DESC", $limit, $page));
}
function captcha()
{
$this->Captcha->render();
}
function view($id = null) {
if(!$id) {
$this->Session->setFlash('Invalid id for Guestbook Entry.');
$this->redirect('/guestbook_entries/index');
}
$this->set('guestbookEntry', $this->GuestbookEntry->read(null, $id));
}
function add() {
if(empty($this->data)) {
} else {
$captcha = $this->Session->read("captcha");
if ($captcha == $this->data['GuestbookEntry']['captcha']) {
$this->data['GuestbookEntry']['name'] = htmlentities($this->data['GuestbookEntry']['name']);
if($this->GuestbookEntry->save($this->data)) {
$this->Session->setFlash('The Guestbook Entry has been saved');
$this->redirect('/guestbook_entries/index');
} else {
$this->Session->setFlash('Please correct errors below.');
}
}
}
}
function edit($id = null) {
if(empty($this->data)) {
if(!$id) {
$this->Session->setFlash('Invalid id for Guestbook Entry');
$this->redirect('/guestbook_entries/index');
}
$this->data = $this->GuestbookEntry->read(null, $id);
$this->set('users', $this->GuestbookEntry->User->generateList());
} else {
$this->cleanUpFields();
if($this->GuestbookEntry->save($this->data)) {
$this->Session->setFlash('The GuestbookEntry has been saved');
$this->redirect('/guestbook_entries/index');
} else {
$this->Session->setFlash('Please correct errors below.');
$this->set('users', $this->GuestbookEntry->User->generateList());
}
}
}
function delete($id = null) {
if(!$id) {
$this->Session->setFlash('Invalid id for Guestbook Entry');
$this->redirect('/guestbook_entries/index');
}
if($this->GuestbookEntry->del($id)) {
$this->Session->setFlash('The Guestbook Entry deleted: id '.$id.'');
$this->redirect('/guestbook_entries/index');
}
}
}
?>

Nun folgen noch die views, gepackt in den Ordner views/guestbook_entries

index.thtml


<?php $pagination->setPaging($paging); ?>
<div class="guestbookEntries">
<h2>Guestbook</h2>
<h3>Spammers will be shot!</h3>
<?php echo $html->link($html->image("neu.gif"), '/guestbook_entries/add', NULL,NULL,FALSE); ?>
<? echo $this->renderElement('pagination');
$i=0;?>
<table cellpadding="0" cellspacing="0" class="gbook_table">
<?php foreach ($guestbookEntries as $guestbookEntry):
$gbook = ($i++%2 == 0) ? "gbook_class1" : "gbook_class2";
echo "<tr class=\"".$gbook."\">";
?>
<td rowspan="3" class="gbook_number"><?php echo $guestbookEntry['GuestbookEntry']['id']; ?></td>
<td colspan="2"><?php echo $guestbookEntry['GuestbookEntry']['name']; ?> schrieb am <?php echo $deutsch->de_date($guestbookEntry['GuestbookEntry']['created'],2); ?> </td>
<?php echo "</tr><tr class=\"".$gbook."\">";?>
<td colspan="2"><?php echo $guestbookEntry['GuestbookEntry']['content']; ?></td>
<?php echo "</tr><tr class=\"".$gbook."\">";?>
<td nowrap>
<?php echo $html->link('Bearbeiten','/guestbook_entries/edit/' . $guestbookEntry['GuestbookEntry']['id'])?>
<?php echo $html->link('Löschen','/guestbook_entries/delete/' . $guestbookEntry['GuestbookEntry']['id'], null, 'Are you sure you want to delete id ' . $guestbookEntry['GuestbookEntry']['id'])?>
</td>
</tr>
<?php endforeach; ?>
</table>
<? echo $this->renderElement('pagination');?>
</div>

edit.thtml


<h2>Edit Guestbook Entry</h2>
<form action="<?php echo $html->url('/guestbook_entries/edit/'.$html->tagValue('GuestbookEntry/id')); ?>" method="post">
<div class="required">
<?php echo $form->labelTag('GuestbookEntry/user_id', 'User');?>
<?php echo $html->selectTag('GuestbookEntry/user_id', $users, $html->tagValue('GuestbookEntry/user_id'), array(), array(), false);?>
<?php echo $html->tagErrorMsg('GuestbookEntry/user_id', 'Please select the User.') ?>
</div>
<div class="required">
<?php echo $form->labelTag('GuestbookEntry/author', 'Author');?>
<?php echo $html->input('GuestbookEntry/author', array('size' => '60'));?>
<?php echo $html->tagErrorMsg('GuestbookEntry/author', 'Please enter the Author.');?>
</div>
<div class="required">
<?php echo $form->labelTag( 'GuestbookEntry/entry', 'Entry' );?>
<?php echo $html->textarea('GuestbookEntry/entry', array('cols' => '60', 'rows' => '10'));?>
<?php echo $html->tagErrorMsg('GuestbookEntry/entry', 'Please enter the Entry.');?>
</div>
<?php echo $html->hidden('GuestbookEntry/id')?>
<div class="submit">
<?php echo $html->submit('Save');?>
</div>
</form>


add.thtml


<h2>Guestbook</h2>
<form action="<?php echo $html->url('/guestbook_entries/add'); ?>" method="post">
<fieldset><legend>Eintrag vornehmen</legend>
<p>Bitte einen Autor und einen Text eingeben. Danach noch das Captcha richtig schreiben und dein Eintrag wird gespeichert</p>
<?php echo $html->tagErrorMsg('GuestbookEntry/name', 'Autor eingeben');?>
<p>Autor:<br><?php echo $html->input('GuestbookEntry/name', array('size' => '40'));?></p>
<?php echo $html->tagErrorMsg('GuestbookEntry/content', 'Please enter the Entry.');?>
<p>Deine Nachricht:<br><?php echo $html->textarea('GuestbookEntry/content', array('cols' => '30', 'rows' => '10'));?></p>
<p>Wenn du das Captcha nicht lesen kannst, lade die Seite neu, dein Text bleibt gespeichert.</p>
<p><img src="<?php echo $html->url('/guestbook_entries/captcha'); ?>" /><br>
<?php echo $html->input("GuestbookEntry/captcha", array('style' => 'width: 116px'));?></p>
<div class="submit">
<?php echo $html->submit('Kommentar hinzufügen', array("class"=>"formsubmit"));?>
</div>
</fieldset>
</form>
<ul class="actions">
<li><?php echo $html->link('Zurück zum Guestbook', '/guestbook_entries/index')?></li>
</ul>

Dies sollte genügen, um ein funktionierendes Guestbook auf euren CakePHP Seiten zu erstellen.

Hoffe ich zumindest, schließlich ist ja Sonntag

PS: Ich suche derzeit dringend nach einem guten Code Einfüge Plugin…
