How to validate if uploaded file is an image? [file sent via HTML5's File API, received via php://input]


Tag : php , By : Ambarish Singh

To fix the issue you can do If it's an image will you store it on disk? If yes, then I'd say the best way would be to create a temporary file, write the data and then check if it's an image with the regular functions, if it is move the temporary file to the final destination, otherwise just delete it.
If for some reason you don't want to do this you can check for magic numbers in the incoming data (here is a more complete list). However bare in mind that this is more likely to fail than the usual solutions.

ColdFusion: No data was received in the uploaded file

Does that help My error report told me that an error has occurred when an user tried uploading an empty file to my server (don't ask why the user did that - I don't know) and now I want to catch that exception which said "No data was received in the uploaded file". I wonder if there is a better way than putting a around the like this: , Try/Catch is the way I usually handle it.
<cftry>
    <cffile action="upload" ...>

    <cfcatch type="any">
        <cfif Find("Saving empty (zero-length) files is prohibited", CFCatch.Detail) GT 0>

            <!--- Create a zero length file on disk and continue processing as usual --->
            <cffile action="write" file="..." output="">
        <cfelse>
            <cfrethrow>
        </cfif>
    </cfcatch>
</cftry>

wish helps you I have run into similar problems before. This happens if you execute the following line once
files ={"uploadedfile": ("file1.csv", open("file1.csv", 'rb'))}
requests.post(url, files=files)

I wish this helpful for you I am sending an uploaded file from the html view to the controller using ajax but the file is received as null in the controller. , You may pass data something like in bellow code.
   $("#form0").submit(function (event) {
        var dataString;
        event.preventDefault();
        event.stopImmediatePropagation();
        var action = $("#form0").attr("action");
        if ($("#form0").attr("enctype") == "multipart/form-data") {
            dataString = new FormData($("#form0").get(0));
            contentType = false;
            processData = false;
        } else {
            // regular form, do your own thing if you need it
        }
        $.ajax({
            type: "POST",
            url: action,
            data: dataString,
            dataType: "json",
            contentType: contentType,
            processData: processData,
            success: function (data) {

            },
            error: function (jqXHR, textStatus, errorThrown) {

            }
        });
    });
