Bien, tengo las carpetas involucradas con permisos '777', es decir, todos.
al final del codigo estan los unlink();
Lo que deseo es mostrar la imagen, y cuando se muestre borrarla del servidor, la unica manera que se me ocurrio fue hacer esto, si conocen otra agradeceria que me lo comunicacen ...
Si hay alguna funcion unix que se pueda ejecutar con php para borrar el contenido de una carpeta o algo ...
Código PHP:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
include("conexion.php");
$idir = "images/"; // Path To Images Directory
$tdir = "images/thumbs/"; // Path To Thumbnails Directory
if ($_POST['width'] > 800 && $_POST['height'] > 800){
echo "Measures introduced should be less than 1024 pixels";
?>
<script LANGUAGE="JavaScript">
function redireccionar()
{
javascript:history.go(-1)
}
setTimeout ("redireccionar()", 5000);
</script>
<?php
exit; }
$twidth = $_POST['width']; // Maximum Width For Thumbnail Images
$theight = $_POST['height']; // Maximum Height For Thumbnail Images
$prefijo = substr(md5(uniqid(rand())),0,5); //Random Pref
// Uploading/Resizing Script
$url = $_FILES['imagefile']['name']; // Set $url To Equal The Filename For Later Use
if ($_FILES['imagefile']['type'] == "image/jpg" || $_FILES['imagefile']['type'] == "image/jpeg" || $_FILES['imagefile']['type'] == "image/pjpeg") {
$file_ext = strrchr($_FILES['imagefile']['name'], '.'); // Get The File Extention In The Format Of , For Instance, .jpg, .gif or .php
$copy = copy($_FILES['imagefile']['tmp_name'], "$idir".$prefijo."_" . $_FILES['imagefile']['name']); // Move Image From Temporary Location To Permanent Location
if ($copy) { // If The Script Was Able To Copy The Image To It's Permanent Location
print 'Image uploaded successfully.<br />'; // Was Able To Successfully Upload Image
$simg = imagecreatefromjpeg("$idir".$prefijo."_" . $url); // Make A New Temporary Image To Create The Thumbanil From
$currwidth = imagesx($simg); // Current Image Width
$currheight = imagesy($simg); // Current Image Height
if ($currheight > $currwidth) { // If Height Is Greater Than Width
$zoom = $twidth / $currheight; // Length Ratio For Width
$newheight = $theight; // Height Is Equal To Max Height
$newwidth = $currwidth * $zoom; // Creates The New Width
} else { // Otherwise, Assume Width Is Greater Than Height (Will Produce Same Result If Width Is Equal To Height)
$zoom = $twidth / $currwidth; // Length Ratio For Height
$newwidth = $twidth; // Width Is Equal To Max Width
$newheight = $currheight * $zoom; // Creates The New Height
}
$dimg = imagecreate($newwidth, $newheight); // Make New Image For Thumbnail
imagetruecolortopalette($simg, false, 256); // Create New Color Pallete
$palsize = ImageColorsTotal($simg);
for ($i = 0; $i < $palsize; $i++) { // Counting Colors In The Image
$colors = ImageColorsForIndex($simg, $i); // Number Of Colors Used
ImageColorAllocate($dimg, $colors['red'], $colors['green'], $colors['blue']); // Tell The Server What Colors This Image Will Use
}
imagecopyresized($dimg, $simg, 0, 0, 0, 0, $newwidth, $newheight, $currwidth, $currheight); // Copy Resized Image To The New Image (So We Can Save It)
imagejpeg($dimg, "$tdir".$prefijo."_" . $url); // Saving The Image
imagedestroy($simg); // Destroying The Temporary Image
imagedestroy($dimg); // Destroying The Other Temporary Image
print 'Image resized created successfully. <br />'; // Resize successful
echo '<img src="images/thumbs/'.$prefijo.'_'.$url.'" /> <br />';
} else {
print '<font color="#FF0000">ERROR: Unable to upload image.</font> <br />'; // Error Message If Upload Failed
}
} else {
print '<font color="#FF0000">ERROR: Wrong filetype (has to be a .jpg or .jpeg. Yours is '; // Error Message If Filetype Is Wrong
print $file_ext; // Show The Invalid File's Extention
print '.</font> <br />';
unlink("$tdir".$prefijo."_" . $url);
unlink("images/f7105_18.jpg");
} ?>
Saludos
PD: el ultimo unlink esta asi porque lo use de prueba para ver si me borraba un archivo seleccionado pero asi no funciono tampoco.
