For the longest time, I've been using a very standard HTML post to my PHP upload script for my image upload. I wanted to try something new by sending the image to the PHP uplaod script via JQuery/JSON. All text data on my site is sent through this and I wanted to try and get image uploads to work with JQUery. I googled, but only found pre-made scripts, no one ever has a tutorial on making it yourself or where to begin, there's nothing wrong with using premade scripts but alot of times I can't get it to work with my website or style it so that it fits in, so I began to write a quick something, can you guys please tell me if this would work being that an image isn't text data?
My HTML:
<div class="upload_box_logged">
<input type="file" id="file_up"><br />
<button id="up_btn">Upload</button>
<em style="display:none; color:red;" id="no_file" >Please Select a File!</em>
<em style="display:none; color:red;" id="up_fail" >Failed!</em>
<em style="display:none; color:red;" id="up_success" >Success!</em>
</div>
My JQuery:
$('#up_btn').click(function(){
var fileCheck = $('#file_up').val();
if(fileCheck == '')
{
$('#no_file').fadeIn();
}
else
{
var file_upVar = encodeURIComponent($('#file_up').val());
$.ajax({
type: 'POST', url: 'upload.php', dataType: "json", data: { file_up: file_upVar },
success: function(result) {
if (!result.success) { $('#up_fail').fadeIn().fadeOut(5000); }
else { $('#up_success').fadeIn().fadeOut(5000); }
}
});
}
});
Now here's my PHP file that I've been using with my standard HTML post to PHP method:
$file_name = $HTTP_POST_FILES['ufile1']['name'];
$file_name_for_db = ($HTTP_POST_FILES['ufile1']['name']);
$new_file_name = $id."_pic1_".$file_name;
$allowedTypes = array("image/jpg", "image/jpeg", "image/png");
$maxSize = 5 * 1024 * 1024; // 3Mb
$fileType = $HTTP_POST_FILES['ufile1']["type"];
$fileSize = $HTTP_POST_FILES['ufile1']["size"];
// check if there was an error
if ($HTTP_POST_FILES['ufile1']["error"] > 0)
{
die($HTTP_POST_FILES['ufile1']["error"]);
}
// check if the filetype is valid
if (!in_array($fileType, $allowedTypes))
{
die("Invalid file type: $fileType");
}
// check if the size doesn't exceed the limitations
if ($fileSize > $maxSize)
{
die("The file was too big: $fileSize");
}
$name = $HTTP_POST_FILES['ufile1']["name"];
$tmpfile = $HTTP_POST_FILES['ufile1']["tmp_name"];
// check if the filename is valid
if (preg_match("/[\w-]+\.(jpg|jpeg|png)$/", $name) != 1)
{
die("Invalid file name: $name");
}
$path = "../pic/";
move_uploaded_file($tmpfile, $path);
I will obviously have to de-code the post with something like this.. well I would if this is a correct way of going about it.
$uploaded_file = htmlspecialchars(trim(urldecode($_POST['file_up'])));
Well this is how I'd do it if it were text. Any way I can do this with image data?
Thanks a bunch -Mike
