Bonjour,

J'ai un petit soucis avec mon code :

<?php

class Comment
{
	private $data = array();
	
	public function __construct($row)
	{
		/*
		/	The constructor
		*/
		
		$this->data = $row;
	}
	
	public function markup()
	{
		/*
		/	This method outputs the XHTML markup of the comment
		*/
		
		// Setting up an alias, so we don't have to write $this->data every time:
		$d = &$this->data;
		
		$link_open = '';
		$link_close = '';
		
		if($d['url']){
			
			// If the person has entered a URL when adding a comment,
			// define opening and closing hyperlink tags
			
			$link_open = '<a href="'.$d['url'].'">';
			$link_close =  '</a>';
		}
		
		// Converting the time to a UNIX timestamp:
		$d['dt'] = strtotime($d['dt']);
		
		// Needed for the default gravatar image:
		$url = 'http://'.dirname($_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"]).'/img/default_avatar.gif';
		
		return '
			<div class="comment">
				<div class="avatar">
					'.$link_open.'
					<img src="http://www.gravatar.com/avatar/'.md5($d['email']).'?size=50&default='.urlencode($url).'" />
					'.$link_close.'
				</div>
				
				<div class="name">'.$link_open.$d['name'].$link_close.'</div>
				<div class="date" title="Ajouté '.date('H:i \l\e d M Y',$d['dt']).'">'.date('d M Y',$d['dt']).'</div>
				<p>'.$d['body'].'</p>
			</div>
		';
	}
	
	public static function validate(&$arr)
	{
		/*
		/	This method is used to validate the data sent via AJAX.
		/
		/	It return true/false depending on whether the data is valid, and populates
		/	the $arr array passed as a paremter (notice the ampersand above) with
		/	either the valid input data, or the error messages.
		*/
		
		$errors = array();
		$data	= array();
		
		// Using the filter_input function introduced in PHP 5.2.0
		
		if(!($data['email'] = filter_input(INPUT_POST,'email',FILTER_VALIDATE_EMAIL)))
		{
			$errors['email'] = 'Entrez un email correct';
		}
		
		if(!($data['url'] = filter_input(INPUT_POST,'url',FILTER_VALIDATE_URL)))
		{
			// If the URL field was not populated with a valid URL,
			// act as if no URL was entered at all:
			
			$url = '';
		}
		
		// Using the filter with a custom callback function:
		
		if(!($data['body'] = filter_input(INPUT_POST,'body',FILTER_CALLBACK,array('options'=>'Comment::validate_text'))))
		{
			$errors['body'] = 'Veuillez publier un commentaire';
		}
		
		if(!($data['name'] = filter_input(INPUT_POST,'name',FILTER_CALLBACK,array('options'=>'Comment::validate_text'))))
		{
			$errors['name'] = 'Veuillez donner votre pseudo';
		}
		
		if(!empty($errors)){
			
			// If there are errors, copy the $errors array to $arr:
			
			$arr = $errors;
			return false;
		}
		
		// If the data is valid, sanitize all the data and copy it to $arr:
		
		foreach($data as $k=>$v){
			$arr[$k] = mysql_real_escape_string($v);
		}
		
		// Ensure that the email is lower case:
		
		$arr['email'] = strtolower(trim($arr['email']));
		
		return true;
		
	}

	private static function validate_text($str)
	{
		/*
		/	This method is used internally as a FILTER_CALLBACK
		*/
		
		if(mb_strlen($str,'utf8')<1)
			return false;
		
		// Encode all html special characters (<, >, ", & .. etc) and convert
		// the new line characters to <br> tags:
		
		$str = nl2br(htmlspecialchars($str));
		
		// Remove the new line characters that are left
		$str = str_replace(array(chr(10),chr(13)),'',$str);
		
		return $str;
	}

}

Je l'ai trouvé sur internet, il m'a permis de créer un système de commentaire. Mais mon problème est que j'aimerai que mes membres puissent choisir eux même leur avatar (il l'aurait préalablement indiqué lors de leur inscription.

// Needed for the default gravatar image:
		$url = 'http://'.dirname($_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"]).'/img/default_avatar.gif';
		
		return '
			<div class="comment">
				<div class="avatar">
					'.$link_open.'
					<img src="http://www.gravatar.com/avatar/'.md5($d['email']).'?size=50&default='.urlencode($url).'" />
					'.$link_close.'
				</div>

Je sais que c'est dans cette partie de code qu'il faut que je modifie quelque chose mais je ne sais pas comment faire.

J'imagine aussi qu'il va falloir utiliser les sessions php et une condition.

Voilà a quoi ressemble le système de commentaire :



Auriez-vous une idée ?

Merci d'avance
