PHP - Upload multiple images
so started code found on http://lpmj.net/7.php (example 15) uploads image, writes variable, , displays it. want modify instead writes array , displays, , can continue upload images subsequent array position , display them all, opposed recent, case now. can see set put in array , after displaying, move next position, given html creates button not dynamic, sort of stuck. here's have now:
thanks!code:<?php // upload.php $m=0; echo <<<_end <html><head><title>php form upload</title></head><body> <form method='post' action='upload.php' enctype='multipart/form-data'> select file: <input type='file' name='filename' size='10' /> <input type='submit' value='upload' /> </form> _end; display(); function display(){ if ($_files) { $name[$m] = $_files['filename']['name']; move_uploaded_file($_files['filename']['tmp_name'], $name[$m]); echo "uploaded image '$name[$m]'<br /><img src='$name[$m]' />"; $m++; } } echo "</body></html>"; ?>
two things:
[1] if write array contents won't persist between uploads. if need store image locations, need store them flat file or database.
[2] if want, can include multiple <inputs> on page, so:
then access:code:<input type='file[]' name='filename' size='10' /> <input type='file[]' name='filename' size='10' /> <input type='file[]' name='filename' size='10' /> <input type='file[]' name='filename' size='10' />
etc.code:$name = array(); $name[0] = $_files['filename']['name'][0] $name[1] = $_files['filename']['name'][1] $name[2] = $_files['filename']['name'][2] $name[3] = $_files['filename']['name'][3]
[3] dynamically add/remove inputs, may quickest use client side javascript.
