$_FILES["imgs"] meerdere bestanden
Ik heb een pagina waar een berichtje plus een of meerdere foto's geupload kunnen worden.
Nu zit ik echter met het probleem dat ik bij selecteren van 2 foto's, de eerste 5x doorlopen wordt (bij de 1e keer succesvol geupload wordt en bij de 4x erna vastloopt omdat het TMP bestand er neit meer is (duh)) en de tweede niet.
Hieronder de code, ik denk dat de fout 'm zit in regel 21.

Dus wat ik bedacht is om bij elke $_Files["imgs"][ding] een [$i] (teller) erachter te zetten.
Wat dat doet is over elke letter van de filename loopen...
Sorry, maar ik zie het niet :(

Doe eens een print_r($_FILES) dan zie je hoe het in elkaar zit.
Laat het resultaat eens zien.
Code (php)
1
2
2
echo("<br>Size array: " . count($_FILES) . "<br>");
print_r($_FILES);
print_r($_FILES);
Met dit stukje tekst krijg ik de output:
Code (php)
1
2
2
Size array: 1
Array ( [imgs] => Array ( [name] => foto.jpg [type] => image/jpeg [tmp_name] => /tmp/phpBT0baw [error] => 0 [size] => 1344938 ) )
Array ( [imgs] => Array ( [name] => foto.jpg [type] => image/jpeg [tmp_name] => /tmp/phpBT0baw [error] => 0 [size] => 1344938 ) )
Vul ik bij de eerste regel echter count($_FILES["imgs"]), dan wordt de size 5 (namelijk: de 5 dingen name, type, tmpname, error en size). Tot zover begrijp ik het.
Wat ik niet begrijp, is waarom array size 1 is waar het 2 moet zijn - oh toch wel.
Een array begint op index 0, en count geeft de laatste index terug dus moet ik loopen over
Code (php)
1
for($i=0; $i<=count($_FILES); $i++) { //$i<= ipv $i<
Nope. werkt niet. (Die teller ook geprobeerd ergens te zetten waar de filename geprint wordt om zo te kijken waar die in de rest van de code staan moet, maar dit was geen succes...
