Question

I have given 2 option(upload icon/select icon) in form, but when i am checking it with php its throwing error...

html

<label class="tagslabel">Upload Icon</label>
<input name="uploadicon" type="file" />
<span>or</span>
<ul class="icons clearfix">
    <li>
        <input type="radio" value="123456" name="selecticon"/>
        <label for="selecticon">
            <img src="pics/123456.jpg" alt="123456" width="34" height="34" />
        </label>
    </li>
    <li>
        <input type="radio" value="654321" name="selecticon" />
        <label for="selecticon">
            <img src="pics/654321.jpg" alt="654321" width="34" height="34" />
        </label>
    </li>
</ul>

php

if (!empty($_FILES['uploadicon']['name'])) {
     //do image processing and validation
}
else {
    if($_POST['selecticon'] == '') $errors['selecticon'] = 'Please Select An Icon or upload Icon!';
}

but its throwing following error, if i upload image instead of selecting one.

Notice: Undefined index: selecticon

Answer 1

It's possible that the user selects neither of your options, nor uploads a file themselves. In which case you should check for the existence of 'selecticon' in the $_POST superglobal. Something like this:

 if(!isset($_POST['selecticon'] || $_POST['selecticon'] == '') $errors['selecticon'] = 'Please Select An Icon or upload Icon!'

Answer 2

Try changing

if($_POST['selecticon'] == '')

to

if (!isset($_POST['selecticon']))
