Question

I want to know if an image button can be disabled? When the user has added in the number of questions they need:

if (qnum == <?php echo (int)$_SESSION['textQuestion']; ?>)

then I want to disable the image button, but how can this be done?

Below is what I attemted but it didn’t work:

    //HTML

    <a onclick="return plusbutton();">
    <img src="Images/plussign.jpg" width="30" height="30" alt="Look Up Previous Question" class="plusimage" name="plusbuttonrow"/>
    </a>

    ...

    //jquery


    if (qnum == <?php echo (int)$_SESSION['textQuestion']; ?>) {
    $(".plusimage").attr("disabled", "disabled");

}

Answer 1

Don’t use JQuery for that! Use just php
(Do you have an image for the disabled button?? Images/plussignDISABLED.jpg ?? )

EDIT I just changed qnum to a php variable $numberOfQuestions. I suppose this variable will hold the numer of questions that the user has done (same as your javascript qnum I suppose…)

<?php 
if ($numberOfQuestions == $_SESSION['textQuestion']) {
?>
    <img src="Images/plussignDISABLED.jpg" width="30" height="30" alt="Look Up Previous Question" class="plusimage" name="plusbuttonrow"/>


<?php 

}else {

?>

<a onclick="return plusbutton();">
    <img src="Images/plussign.jpg" width="30" height="30" alt="Look Up Previous Question" class="plusimage" name="plusbuttonrow"/>
    </a>

<?php } ?>
