Trouble with file Uploads

jgd12345 · May 28, 2003

My server runs in safe mode but I don't think it's a safe mode restriction. Basically what I've got is a simple for with the enctype thing in the form bit and one of the fields being <input type="file" name="location"> but I'm receiving the following error:

Warning: stat failed for images/1.jpg (errno=2 - No such file or directory) in /home/virtual/site56/fst/var/

http://www/html/forum/item.php

on line 1001

but the directory does exist. Here's the part which does the upload:

if ($location == "&quot

{
exit('Error: No file selected to upload');
} else {
$test = $HTTP_POST_FILES[location][name];
$test = substr($test, -4);

if ($test == ".jpg" XOR $test == ".png" XOR $test == ".gif" XOR $test == ".JPG" XOR $test == ".PNG" XOR $test == ".GIF" XOR $test == "jpeg" XOR $test == "JPEG&quot

{
if ($test == "JPEG" xor $test == "jpeg&quot

{
$test = ".jpeg";
}

$image = "images/1$test";

move_uploaded_file($location, "$image&quot

;
} else {
exit('Error: Wrong File Type');
}

echo 'Successfully added';
}

I'd be greatful for your help. Thanx

I think the problem is that there is no tempory file specified that he must upload/move:

Try this:

$upload_file = $_FILES['location']['name'];
$temp = $_FILES['location']['tmp_name'];
$extension = substr($upload_file,-4);

and then:
$image = "images/1".$extension;
move_uploaded_file($temp, $image);

Cheers worked a treat. I was also wondering how you create a thumbnail. Currently I resize the image using the following but that keeps the same file size ie 70kb. I was wondering if there was something I can do make it smaller. Thanx

if($image[thumbnail] == "no&quot

{
$image[thumbnail] = "$image[imageurl]";
} else {
$image[thumbnail] = str_replace(" ", "%20", $image[imageurl]);
$imageurl = $image[imageurl];

$maxw = 80; // Height of Thumbnail
$maxh = 80; // Width of Thumbnail

$SizeArray = getimagesize($imageurl);

if($SizeArray[0] > $maxw || $SizeArray[1] > $maxh) {
$width = $SizeArray[0];
$height = $SizeArray[1];

$percent = $maxh / $width;
$height = $height * $percent;

if($height > $maxh) {
$percent2 = $maxw / $SizeArray[1];
$SizeArray[0] = $SizeArray[0] * $percent2;
$w = 'width="'.$SizeArray[0].'" height="'.$maxh.'"';
} else {
$w = 'width="'.$maxw.'" height="'.$height.'"';
}
} else {
$image[thumbnail] = str_replace(" ", "%20", $image[thumbnail]);
}
}

To resize an image requires use of the Image family of functions,

http://www.php.net/manual/en/ref.image.php,

or invokation of an external application, like ImagMagick.

Had a read and tried a few things, but didn't really understand it. Thanx anywayz. Do you know of a built in function or one you could let me use which compresses the size of an image (ie if it was located at images/name.gif and its size was 70kb makes it 2kb) and then creates that image aswell. Thanx

Yeah I get the same problems. Here's a basic example of what I'm using:

if($action == "newimage&quot

{
if(!$submit) {
<br>
<form method="post" enctype="multipart/form-data" action="edit.php?action=newimage" name="input">
<table cellspacing="0" cellpadding="0" align="center" class="table">
<tr>
<td bgcolor="$bordercolor">
<table cellspacing="$borderwidth" cellpadding="$tablespace" align="center" width="100%">
<tr>
<td colspan="2" class="header">New Image</td>
</tr>
<tr>
<td bgcolor="$altbg1" class="tablerow">Location:</td>
<td bgcolor="$altbg2" class="tablerow"><input type="file" name="location" class="text"></td>
</tr>
<tr>
<td colspan="2" align="center" bgcolor="$altbg1" class="tablerow"><input type="submit" name="submit" value="Submit" class="submit"></td>
</tr>
</table>
</td>
</tr>
</table>
</form>
} else {
$location = checkInput($location, '', '', 'javascript');

$query = mysql_query("SELECT id FROM $table_media_images ORDER BY id DESC LIMIT 1&quot

;
$nb = $db->fetch_array($query, 0);

$filename = $nb[id] + 1;

if ($location == "&quot

{
exit('Error: No file selected to upload');
} else {
$upload_file = $HTTP_POST_FILES['location']['name'];
$temp = $HTTP_POST_FILES['location']['tmp_name'];
$extension = substr($upload_file, -4);

if ($extension == ".jpg" XOR $extension == ".png" XOR $extension == ".gif" XOR $extension == ".JPG" XOR $extension == ".PNG" XOR $extension == ".GIF" XOR $extension == "jpeg" XOR $extension == "JPEG&quot

{
if ($extension == "JPEG" xor $extension == "jpeg&quot

{
$extension = ".jpeg";
}

$imageurl = "images/$filename$extension";

move_uploaded_file($temp, $imageurl);
} else {
exit('Error: Wrong File Type');
}

echo 'Successfully added';
}

mysql_query("INSERT INTO $table_media_images VALUES('', '$imageurl', '', '', '', '')&quot

;

$outputtext = "Image successfully added!";
eval("\$output = \"".template("output&quot

."\";&quot

;
echo $output;/*
?>

<script>
function redirect() {
window.location.replace("edit.php?action=newimage&quot

;
}
setTimeout("redirect();", 1250);
</script>

<?*/
}
}

To display the images I've just done a loop through the records:

$query = mysql_query("SELECT * FROM $table_media_images&quot

;

while($image = mysql_fetch_array($query)) {
if($image[thumbnail] == "no&quot

{
$image[thumbnail] = "$image[imageurl]";
} else {
$image[thumbnail] = str_replace(" ", "%20", $image[imageurl]);
$imageurl = $image[imageurl];

$maxw = 80; // Height of Thumbnail
$maxh = 80; // Width of Thumbnail

$SizeArray = getimagesize($imageurl);

if($SizeArray[0] > $maxw || $SizeArray[1] > $maxh) {
$width = $SizeArray[0];
$height = $SizeArray[1];

$percent = $maxh / $width;
$height = $height * $percent;

if($height > $maxh) {
$percent2 = $maxw / $SizeArray[1];
$SizeArray[0] = $SizeArray[0] * $percent2;
$w = 'width="'.$SizeArray[0].'" height="'.$maxh.'"';
} else {
$w = 'width="'.$maxw.'" height="'.$height.'"';
}
} else {
$image[thumbnail] = str_replace(" ", "%20", $image[thumbnail]);
}
}

echo '<img src="'.$image[thumbnail.'" $w><br>';
}

I understand what your saying, However I am buying books and books on php along with php.net and tek-tips to teach my self php and I for the most part am coming along it is just the uploading and displaying an image where I can not grasp the idea. I just need minor help here. I know that what I am doing wrong is a little simple thing.
