Display A 'div' Box Only When A Specific Checkbox Is Selected
I have the next form in a Wordpress plugin and I want to display the 'div' box with the 'Price' text field only when the checkboxes 'Not free 1' or 'Not free 2' are checked. I know
Solution 1:
I think the options should be radio buttons instead of checkboxes. This code will help you get started:
var advertNodes = $('#advert_category-1, #advert_category-2 ');
var advertInput = $('.adverts-field-text');
advertNodes.click(function() {
if (!advertNodes.is(':checked')) {
advertInput.hide();
}
else {
advertInput.show();
}
});
Solution 2:
Finally I have arrived to this working solution:
// a form in a plugin (not mine):
<form action="" method="post">
<fieldset><div><labelfor="category">Categories</label><selectid="category"name="category"><optionvalue="">Select Options ...</option><optionvalue="2">Free</option><optionvalue="4">Not free 1</option><optionvalue="7">Not free 2</option></select></div><div><labelfor="price">Price</label><inputname="price"id="price"type="text"></div></fieldset></form>// another plugin (*display-price.php*) (this is mine)add_action( 'wp_enqueue_scripts', 'add_my_script' );
functionadd_my_script() {
wp_enqueue_script(
'display-price',
plugins_url( '/display-price.js' , __FILE__ ),
array('jquery')
);
}
// a jQuery (*display-price.js*) to display the 'div' box with// the 'Price' text field only when the option 'Not free 1' or// 'Not free 2' are selectedjQuery(document).ready(function($) {
var cat = ["4", "7"]; // option values for which the price field is displayed
$("#price").parent('div').hide();
$('#category').change(function(){
if($.inArray($('#category').val(), cat) > -1) {
$("#price").parent('div').show();
} else {
$("#price").parent('div').hide();
}
});
});
Both display-price.php and display-price.js files are located in the same directory (the default Wordpress plugins directory).
