When using PHP, JavaScript, and HTML, you can trigger an image upload immediately after choosing a file using the

I currently have a small form with two buttons - one for browsing and another for uploading an image. I feel that having two separate buttons for this purpose is unnecessary.

Is there a way to combine the browse and upload functions into just one button?

Here is the code snippet that relates to this issue: (When the upload button is clicked, it triggers a JavaScript function that calls a PHP file to handle the upload process)

<form class="jQ-form" action="includes/ajaxupload.php" method="post" name="standard_use" id="standard_use" enctype="multipart/form-data">
    <fieldset>  
        <button id="image_upload_button" style="float:left;"  onclick= "$('#upload_area').css('display','none');
        $('#upload_area').fadeIn('slow');ajaxUpload(this.form,'includes/ajaxupload.php?filename=filename&amp;maxSize=200000&amp
        ... more func data.'); return false;" disabled>upload icon</button>

        <input type="file" id="upload_file" name="filename" style="float:left;width:70%;" size="42"/>

        <p style="float:right;color:#a2983c;margin:10px;width:373px;">
        Pick a nice icon that is max 300x300 pixels please
        </p>

        <?php 
            echo '<div id="upload_area" style="'.((($theiconname!='') && (file_exists($thumb_path.$theiconname))) ? '' : 'display:none;').'float:left;
            width:50px;height:50px;border:3px solid #000;margin-top:12px;margin-left:3px;">';
            if ($theiconname){

                if (file_exists($thumb_path.$theiconname))
                {
                    echo'<img id="the_logo" src="'.$thumb_path.$theiconname.'"/>';
                }

            }
        ?>
        </div>
    </fieldset>
</form>

I would appreciate any help or suggestions on how to streamline this process! Thanks in advance!

Answer №1

A simple solution is to detect when the file input field changes and then submit the parent form. Since you are using jQuery, here is a code snippet that accomplishes this:

$("#upload_file").change( function(){
     $("#standard_use").submit();
});

If you are handling the submission via AJAX instead of submitting the form directly, you can replace $("#standard_use").submit(); with the appropriate function that should be triggered when the user clicks on your "upload image" button.
