The PHP function used in WordPress to get the search form is parsed

The Get_search_form function is used in WordPress to extract a preset search form or a default search form. Because the official this function is not Chinese, so I wrote it briefly.

Describe
The Get_search_form function is used in WordPress to extract custom search forms or default search forms.
Whether the custom form is displayed or the default form is displayed depends entirely on the search.php file in your theme.
If the file is present, the file is called automatically, and if not, the default search form is displayed.

Use

<?php  get_search_form ($echo = True)?>

Parameters
$echo Boolean that is used to select whether to display or return variables.
Default value: True

Instance
Not as complicated as you might think, it's really that simple.

<?php  get_search_form ();?>

Mention here, if you need to integrate Google custom search for those words,
You just have to put the custom part of the code in your search.php file, and of course you need to set the style.

Function source Code

<?php/** * Display search form. * Would first attempt to locate the searchform.php file in either the child or the parent and then load it. If it doesn ' t exist, then the default search form * would be displayed.
