This is a search form which i want to design. I have created this form in a page template named isbn. But when i am opening that page for editing i am unable to do this. I am using divi theme in wordpress.
So divi theme is not allowing me to edit this page. Due to which this page is looking very bad in look wise.
Can anyone help me for designing this page by giving their codes or simply by giving their suggestions?
I am facing one more problem whenever i am writing css code in above code i am not getting anything. So i am totally blank that how to deal with this
Just create a WordPress page and add shortcode which you added in functions.php before. Don't create template for this page just use your shortcode only.
First, you have to create a page using divi theme, then create shortcode for this form in functions.php and then use this shortcode in your page.
you are inserting the form above the get_header(); function, so it will be outside of the html tag and outside of the body tag. Move it into the body, then it should at least appear on the page, and you'll see what you need to do next.

You can place all your form handlers on the same page, but be sure to place them before any output. Like this:
<?
if (isset($_POST['my-form-submit'])) : // check if form is submitted
/*
Here goes update process etc
*/
endif;
get_header();
?>
<form action="<?php echo $_SERVER['REQUEST_URI']; ?>" method="POST">
/* Here come form fields */
<input type="submit" name="my-form-submit" value="Update" />
</form>
<?php
get_footer();
?>
Introduction:
At this moment I'm creating my first custom Wordpress theme. Now I succesfully created a HTML/CSS template and converted this to fit wordpress (including header.php, index.php, footer.php, functions.php, sidebar.php and page.php).
Case/Problem definition:
At my homepage (index.php), I included several div's filled with text (pure HTML and CSS). Now I want to be able to manually change this text from an admin panel in my Wordpress Back-end. I already made an extra sub-menu page in the admin panel. This page is completely blank at this moment.
In Short:
How to fill in a text form in my Wordpress admin panel and echo this out on a certain page (front-end).
Extra
Since I'm new to Wordpress, PHP and creating your own themes I'm not sure how to do this or how to search for tutorials online (I don't know the correct terminology to search).
Thanks for all the tips and advice already!
In your functions.php add the following code that is highlighted. This will add a twitterid. So anywhere in your custom theme you can call the value of the custom admin page:
add menu item:
add_action('admin_menu', 'add_global_custom_options');
Assign the custom function which will create a form.
function add_global_custom_options()
{
add_options_page('Global Custom Options', 'Global Custom Options', 'manage_options', 'functions','global_custom_options');
}
Create a Function Which Generates the Form:
<?php
function global_custom_options()
{
?>
<div class="wrap">
<h2>Global Custom Options</h2>
<form method="post" action="options.php">
<?php wp_nonce_field('update-options') ?>
<p><strong>Twitter ID:</strong><br />
<input type="text" name="twitterid" size="45" value="<?php echo get_option('twitterid'); ?>" />
</p>
<p><input type="submit" name="Submit" value="Store Options" /></p>
<input type="hidden" name="action" value="update" />
<input type="hidden" name="page_options" value="twitterid" />
</form>
</div>
<?php
}
?>
View your admin page. You will find a new link in your Admin Menu called “Global Custom Options”. Just enter your values in that form and you are good to go for using those values in your theme files like “get_option(‘twitterid’)”. So, in your index.php or any other theme file, you can do something like
<?php echo get_option('twitterid') ?>
and it will print whatever value is in the textbox on admin page.
Here is a link to the tutorial for reference.
I am working on a plugin, which creates a couple of Virtual pages, and I wish these links to be available in Menu admin page, to let users have the liberty to add them as they create menus.
I want to add a Meta box in Menu administration, very similar to Page/Category meta boxes, to let users select what page to add in their menu.
Apparently, the only possible research is in the core itself.
Here, /wp-includes/nav-menu.php, we can get how to insert the meta box:
add_action('admin_init', 'so_13875144_nav_menu_meta_box');
function so_13875144_nav_menu_meta_box() {
add_meta_box(
'my-custom-nav-box',
__('Custom Box'),
'so_13875144_display_menu_custom_box',
'nav-menus',
'side',
'default'
);
}
function so_13875144_display_menu_custom_box() {
/* Not sure about this global var */
//global $_nav_menu_placeholder;
//$_nav_menu_placeholder = ( 0 > $_nav_menu_placeholder ) ? intval($_nav_menu_placeholder) - 1 : -1;
?>
<p id="menu-item-custom-box">
<label class="howto" for="custom-menu-item-custom-box">
<span><?php _e('URL'); ?></span>
<input id="custom-menu-item-custom-box" name="menu-item[<?php echo $_nav_menu_placeholder; ?>][menu-item-custom-box]" type="text" class="code menu-item-textbox" value="my text" />
</label>
</p>
<?php
}
But, the hard part, which I haven't managed to make work, is to save the value.
This is the file /wp-admin/nav-menus.php that has to be studied.
Tried to hook into the action wp_update_nav_menu, but the custom meta box input field is not being passed into $_POST.
WordPress Answers may have some hint: https://wordpress.stackexchange.com/search?q=wp_update_nav_menu
http://codex.wordpress.org/Function_Reference/add_meta_box
Use the post_type 'nav-menus'
I know I'm late to the party but just for anyone else trying to do this...
b__ is right, that is the way to get it to show on the page except it is much easier to use checkboxes than any other field because there is an inbuilt javascript function that looks for checkboxes.
All you need to do is copy the html from an existing checkbox -
<li><label class="menu-item-title"><input type="checkbox" class="menu-item-checkbox" name="menu-item[-1][menu-item-object-id]" value="2"> Sample Page</label><input type="hidden" class="menu-item-db-id" name="menu-item[-1][menu-item-db-id]" value="0"><input type="hidden" class="menu-item-object" name="menu-item[-1][menu-item-object]" value="page"><input type="hidden" class="menu-item-parent-id" name="menu-item[-1][menu-item-parent-id]" value="0"><input type="hidden" class="menu-item-type" name="menu-item[-1][menu-item-type]" value="post_type"><input type="hidden" class="menu-item-title" name="menu-item[-1][menu-item-title]" value="Sample Page"><input type="hidden" class="menu-item-url" name="menu-item[-1][menu-item-url]" value=""><input type="hidden" class="menu-item-target" name="menu-item[-1][menu-item-target]" value=""><input type="hidden" class="menu-item-attr_title" name="menu-item[-1][menu-item-attr_title]" value=""><input type="hidden" class="menu-item-classes" name="menu-item[-1][menu-item-classes]" value=""><input type="hidden" class="menu-item-xfn" name="menu-item[-1][menu-item-xfn]" value=""></li>
but give them each a unique ID and put your details in for the URL, title etc.
Then, add a submit button at the end to add to the menu -
<input type="submit" class="button-secondary submit-add-to-menu right" value="<?php esc_attr_e('Add to Menu'); ?>" name="YOUR NAME" id="YOUR ID" onclick="(function(){$('#THE DIV YOU HAVE PUT YOUR LIST IN').addSelectedToMenu( api.addMenuItemToBottom );})"/>
And that should add the item to the list.
This is a pretty old question but I was trying to do this today so in case it points anyone in the right direction...
I won't cover adding the meta box, as it's covered above. I'll also only cover a custom link as I haven't looked into adding a post, page, term link etc.
Just to cover the logic of how I got there...Looking at wp-admin/js/nav-menu.js, for a custom link you'll want to use window.wpNavMenu.addItemToMenu(). This ajax submits to the function wp_ajax_add_menu_item() in wp-admin/includes/ajax-actions.php. This then submits to wp_save_nav_menu_items() in wp-admin/includes/nav-menu.php. The upshot from looking at these files is that all menu items are of a post_type, taxonomy, post_type_archive or custom type.
Hook the javascript to the HTML as you wish, but if you want to submit a custom link, you need to call addItemToMenu() as follows:
var url = 'http://example.com';
var title = 'Link text';
window.wpNavMenu.addItemToMenu({
'-1': {
'menu-item-type': 'custom',
'menu-item-url': url,
'menu-item-title': title,
}
}, window.wpNavMenu.addMenuItemToBottom);
Menu item type has to be "custom" otherwise it requires info for a post, page etc. with which to associate the menu item.
This is my first try to writing custom plugin in WordPress, Certainly there is a way to add CSRF tag to forms in WordPress and check form validity inside server. The question is how can I?
If you are using Wordpress 2.0.4 or above you can use wp_nonce_field and wp_verify_nonce field to verify. The Wordpress documentation has some examples (which I posted below).
In your form:
<form method="post">
<!-- some inputs here ... -->
<?php wp_nonce_field('name_of_my_action','name_of_nonce_field'); ?>
</form>
In your processing action:
<?php
if ( empty($_POST) || !wp_verify_nonce($_POST['name_of_nonce_field'],'name_of_my_action') )
{
print 'Sorry, your nonce did not verify.';
exit;
}
else
{
// process form data
}
I have added within my WordPress 3.1 site, the following code at the bottom of my sidebar.php file:
<div id="search_box">
<form id="searchform" action="http://www.service.com/" method="get" role="search">
<input id="s" type="text" name="s" class="search" value="Search site" size="19" maxlength="80" id="white_box" onfocus="if (this.value=='Search site') this.value = ''"/>
<input id="searchsubmit" type="image" class="submit" value="submit" src="<?php bloginfo( 'template_url' ); ?>/images/search_btn.jpg" />
</form>
</div>
As I have coded this search process myself, when I place a some text within my search text box and press the "Search" button, it looks as if, is is calling the page search.php within my theme and displaying the results.
Questions:
1) where/how does it know when I press the "Search" button to go off and call search.php?
2) if possible only, how can I change it to call a different php file instead of the search.php
Thanks.
Use template filter
add_filter( 'template_include', 'template_include', 10 );
and change the template as
function template_include($template)
{
if(your condition here){
$template = get_template_directory().'/your-template.php';
}
return $template;
}
-1. All requests for a WP site go to a single page that routes them based upon specific criteria. Thus when a search is performed it knows that it is a search and directs to the search.php page.
Specifically it goes to index.php that loads wp-blog-header.php.
-2: Everything you need to know should be right here: http://codex.wordpress.org/Creating_a_Search_Page#Using_the_page.php
Wordpress assumes the request is a search if it sees an 's' GET variable.
You can hook into the template_redirect action (in your theme's functions.php file) and load a different template like so:
add_action('template_redirect', 'my_template_select');
function my_template_select() {
if (is_search()) {
load_template(TEMPLATEPATH . '/foobar.php');
exit;
}
}
