Files not posting html+js+php

[ardit_620]

I got a field in my HTML that send a file.. When the user selects an image they get a preview of the image they are about to upload (js). When this preview script is activated the \[code\]$_FILES\[/code\] post doesn't send any data (php verified with \[code\]var_dump($_FILES)\[/code\]).Here is the JS:\[code\]function readURL(input) {if (input.files && input.files[0]) { var reader = new FileReader(); reader.onload = function (e) { $('#preview') .attr('src', e.target.result) .css('display', 'block'); $('#upload').html('<i class="icon-upload"></i> <input type="file" onchange="readURL(this);" size="1" name="foto" class="input-file" />Cambiar im&aacute;gen') }; reader.readAsDataURL(input.files[0]); // <- If I delete this line it posts correctly but dosen't preview the image.}\[/code\]Someone sees the error?
