Estoy tratando de hacer un administrador de imagenes...donde pueda subir y eliminar imagenes....
el subir funciona(script desde http://blog.unijimpe.net) ṕero quiero agregarle la funcionalidad de eliminar y no me resulta...los codigos son los siguientes.
Código PHP:
<?php
require("upload.php");
$status = "";
if ($_POST["action"] == "upload") {
$fupload = new Upload();
$fupload->setPath("files");
$fupload->setFile("archivo");
$fupload->isImage(true);
$fupload->save();
$status = $fupload->message;
}
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>PHP upload - Imagen</title>
<link href="estilo.css" rel="stylesheet" type="text/css" />
</head>
<body>
<table width="413" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="413" height="40" class="titulo">PHP upload </td>
</tr>
<tr>
<td class="text">Por favor seleccione el archivo a subir:</td>
</tr>
<tr>
<form action="index.php" method="post" enctype="multipart/form-data">
<td class="text">
<input name="archivo" type="file" class="casilla" id="archivo" size="35" />
<input name="enviar" type="submit" class="boton" id="enviar" value="Upload File" />
<input name="action" type="hidden" value="upload" /> </td>
</form>
</tr>
<tr>
<td class="text" style="color:#990000"><?php echo $status; ?></td>
</tr>
<tr>
<td height="30" class="subtitulo">Listado de Archivos Subidos </td>
</tr>
<tr>
<td class="infsub">
<?php
$i=0;
if ($gestor = opendir('files')) {
echo " <input type='radio' name='delete".$i."' value='/images/".$arch."'>";
while (false !== ($arch = readdir($gestor))) {
if ($arch != "." && $arch != "..") {
echo "<a href=\"files/".$arch."\" class=\"linkli\">".$arch."</a>\n";
}
if( $_POST["delete".$i] == "/images/".$arch ){
echo " NOTA: Se eliminara: ".$_POST["delete".$i];
unlink($_POST["delete".$i]);
}//fin if
}
echo "<br />";
echo "<input type='submit' value='Eliminar' />";
closedir($gestor);
}
?>
</td>
