How to add placeholder to input field via php variable

Question

In my login form, custom layout fields are displayed by the $field->input variable. Unfortunately, those fields are displayed without the placeholder attribute.

Is there any way to add this attribute to the field which is displayed by variable above?

<?php foreach ($this->form->getFieldset($fieldset->name) as $name => $field) : ?>
    <?php if ($field->hidden === false) : ?>
        <div class="sc-group">
            <?php echo $field->input; ?>
        </div>
    <?php endif; ?>
<?php endforeach; ?>

Answer 1

I believe that hint is the attribute you're looking for:

<field name="name"
       label="Name"
       type="text"
       required="true"
       hint="Placeholder Text"
       default=""
/>

You need to follow below steps

1. Go to components/com_yourcomponent/models/forms
2. Find out the xml file which loads that form.
3. Find the fields where you want to add the place holder text.
4. Use hint attribute:<field name="field_name" label="Field Label" type="text" hint="Placeholder Text"/>

Answer 3

you can add a hint field in your xlm or you can add a hint value on the fly in your code here : $field->hint = some text;

<?php foreach ($this->form->getFieldset($fieldset->name) as $name => $field) : 
    $field->hint = JText::_('COM_NAME_FORM_HINT_' . strtoupper($field->fieldname));?>
    <?php if ($field->hidden === false) : ?>
        <div class="sc-group">
            <?php echo $field->input; ?>
        </div>
    <?php endif; ?>
<?php endforeach; ?>
