loop problem 1.0

[Anon]

hi all,

i have problems to pass a file and filename to the target page.

for ($i=0; $i<$Files; $i++){
?>
<p>
<input type="file" name="picture[]">
Name
<input type="text" name="filename[]">
</p>
<?
}

target page should reviece file and filename and create a file.

is it possible to check in a for loop for two arrays? wanna do all in one way.

else {
foreach ($filename, $picture as $key => $val) {

if($val !="") {
	       $return = mysql_query("INSERT INTO files (ID,filename,file) VALUES('$currID','$val','$picture_name')", $link);
	       	if  ($return == false) {
			Error("Die Dateien konnten nicht übertragen werden.<br>".mysql_error());
		}										

		// picture:
		if (($picture != "none") and ($err == false)) {
			// move picture

			if (!copy($picture, "images/$picture_name")) {
			Error("Datei konnte nicht kopiert werden.");
			}
		}									
	}
}												

}

greets,
chris

The problem I see is if a file is supplied but not a filename - your two arrays will slip out of synchronisation with the file list being shorter than the other.

If you're generating the list of File/Name pairs in a loop, you should probably specify their indices explicitly, ie:

for ($i=0; $i<$Files; $i++){
?>
<p>
<input type="file" name="picture[<?=$i?>]">
Name
<input type="text" name="filename[<?=$i?>]">
</p>
<?
}

Then the indices in the two lists will match ($filename[3] always matches up with $picture[3], for example), and you should be safe enough using the keys from one array to access the other:

foreach($picture as $key=>$pic)
{$file=$filename[$key];
//We already have $pic=$picture[$key];
...
}
