How to Add Placeholder Text in Gravity Forms

To do that, you need to open your theme’s functions.php file and paste the following code:

/* Add a custom field to the field editor (See editor screenshot) */
add_action("gform_field_standard_settings", "my_standard_settings", 10, 2);

function my_standard_settings($position, $form_id){
// Create settings on position 25 (right after Field Label)
if($position == 25){
?>
<li class="admin_label_setting field_setting" style="display: list-item; ">
<label for="field_placeholder">Placeholder Text<!-- Tooltip to help users understand what this field does -->
<a href="javascript:void(0);" class="tooltip tooltip_form_field_placeholder" tooltip="&lt;h6&gt;Placeholder&lt;/h6&gt;Enter the placeholder/default text for this field.">(?)</a>
</label>
<input type="text" id="field_placeholder" class="fieldwidth-3" size="35" onkeyup="SetFieldProperty('placeholder', this.value);">
</li>
<?php
}
}

/* Now we execute some javascript technicalitites for the field to load correctly */
add_action("gform_editor_js", "my_gform_editor_js");

function my_gform_editor_js(){
?>
<script>
jQuery(document).bind("gform_load_field_settings", function(event, field, form){
jQuery("#field_placeholder").val(field["placeholder"]);
});
</script>
<?php
}

/* We use jQuery to read the placeholder value and inject it to its field */
add_action('gform_enqueue_scripts',"my_gform_enqueue_scripts", 10, 2);
function my_gform_enqueue_scripts($form, $is_ajax=false){
?>
<script>
jQuery(function(){
<?php
/* Go through each one of the form fields */
foreach($form['fields'] as $i=>$field){
/* Check if the field has an assigned placeholder */
if(isset($field['placeholder']) && !empty($field['placeholder'])){
/* If a placeholder text exists, inject it as a new property to the field using jQuery */
?>
jQuery('#input_<?php echo $form['id']?>_<?php echo $field['id']?>').attr('placeholder','<?php echo $field['placeholder']?>');
<?php
}
}
?>
});
</script>
<?php
}

How To: Enable the Use of Sessions On Your WordPress - [Resolved]

If you want to activate session variables within your WordPress installation the only thing you have to do is call session_start(); before any output is send to the client. Normally upgrading your WordPress installation will replace all files, so we will want to install the code within our site theme to avoid the changes from being lost.

We will add the next lines of code to our functions.php file within our theme:

if ( !session_id() )
add_action( 'init', 'session_start' );


It is best place to add these lines is at the top of functions.php, immediately after the php start tag (<?php).
