Set value and echo “input field”

Question

I want to set value (value="Self_Study") to this input field, I echo this input field as follows

echo '<div class="col-md-4 pull-left hidden self" id="self">
 <input id="' . $SubjectID . '" name="textinput" type="text"  class="input-md tution_provider" placeholder="Self Study" value="Self_Study" disabled>
</div>'

But that value is not echo

how to echo that value ?

Answer 1

Using htmlspecialchars() It nicely worked

echo  '<div class="col-md-4 pull-left hidden self" id="self">
    <input id="' . $SubjectID . '" name="textinput" type="text"  class="input-md tution_provider"  value="' . htmlspecialchars('Self Study') . '" disabled>
    </div>'

Answer 2

试试吧..

echo '<div class="col-md-4 pull-left hidden self" id="self"> <input id="<?php echo $SubjectID; ?>" name="textinput" type="text" class="input-md tution_provider" placeholder="Self Study" value="<?php echo $variable; ?>" disabled> </div>'
