MultiSelect Checkboxes - Options Page WordPress

Louise comments:

Hi there, thanks for your response. I am trying to follow, and cannot get it to work. I updated the name field of my code as you suggested in the first part of the code.

<h3><?php echo $value['name']; ?></h3>
<?php foreach ($value['options'] as $qsoption) { ?>
<label for="<?php echo $qsoption; ?>">
<input type="checkbox" name="myname[]" id="<?php echo $qsoption; ?>" value="<?php echo $qsoption; ?>"
<?php if ( get_option( $value['id'] ) == $qsoption) { echo ' checked="checked"'; } ?> /> <?php echo $qsoption; ?>
</label>
<?php } ?>

Then the second part of my code, I am less certain what to do based on your response. Here is what I changed it to:

if ( isset ($_REQUEST['action']) && ( 'save' == $_REQUEST['action'] ) ){
foreach ( $_REQUEST['myname'] as $myname ) {
if ( array_key_exists('id', $value) ) {
if ( isset( $_REQUEST[ $value['id'] ] ) ) {
update_option( $value['id'], $_REQUEST[ $value['id'] ] );
} else {
delete_option( $value['id'] );
}
}
}

Appreciate your help, thanks!

You can save it directly if your options array is an array:

if ( isset ($_REQUEST['action']) && ( 'save' == $_REQUEST['action'] ) ){
update_option( 'your_option_name', $_REQUEST['myname'] ] );
}
}

Hello again - I have several checkbox options within my plugin options page - some are multiselect, and some are not. Therefore, I need flexibility when options are updated. Can you help me follow the logic of the below code all the way through ( with name="myname[]"):

f ( isset ($_REQUEST['action']) && ( 'save' == $_REQUEST['action'] ) ){
foreach ( $qsoptions as $value ) {
if ( array_key_exists('id', $value) ) {
if ( isset( $_REQUEST[ $value['id'] ] ) ) {
update_option( $value['id'], $_REQUEST[ $value['id'] ] );
} else {
delete_option( $value['id'] );
}
}
}

Thanks!

If you know the names you can do something like:

// for singular options
update_option("singular_option_a", $_REQUEST["singular_option_a"]);

// and the same for multiple options
update_option("multiple_option_a", $_REQUEST["multiple_option_a"]);

Later, when you read it, you will be able to do:
$my_multiple_option = get_option("multiple_option_a");
if(in_array($element, $my_multiple_option))
// do something for activated
else
// do something for disabled

Hello again - Thanks for your help so far. If I understand you correctly, you are suggesting to list out each option separately? Such as "multiple_option_a" and "multiple_option_b" etc. Is there no way to do it more flexibly? I have several options, and would like to avoid listing each one out separately. Thanks.

There are more options but this one, is the most "ordered" one. In any other case, you are going to have problems when you save/load options from database and this is not going to be so easy understand the whole process.

Louise comments:

Hello - thanks for your help so far. I'm still not there. Can you take a look at my code below?

-When you say "if you know the names" of the options, do you mean the ID (i.e. "jqs_select_categories) ?
-Also, I believe get_option in the third area of the code is still based on the ID, which may not link up to "foreach($_REQUEST['myname'] as $myname)...." Thanks!

array (
'name' => 'Categories',
'id' => 'jqs_select_categories',
'type' => 'checkbox',
'options' => $woo_categories,
),
);

else if ( isset ($_REQUEST['action']) && ( 'save' == $_REQUEST['action'] ) ){
foreach($_REQUEST['myname'] as $myname){
if ( isset( $_REQUEST['myname'] ) ) {
update_option( 'jqs_select_categories', $_REQUEST['myname'] );
} else {
delete_option( 'jqs_select_categories' );
}
}


<h3><?php echo $value['name']; ?></h3>
<?php foreach ($value['options'] as $FPFoption) { ?>
<label for="<?php echo $FPFoption; ?>">
<input type="checkbox" name="myname[]" id="<?php echo $FPFoption; ?>" value="<?php echo $FPFoption; ?>"
<?php if ( get_option( $value['id'] ) == $FPFoption) { echo ' checked="checked"'; } ?> />
<?php echo $FPFoption; ?>
</label>

The answer for this two is that we should have here the whole files to see it but, yes, I have seen somes WooCommerce categories here you can:
* Save an array in options with all categories selected by user
* Make a checked function based in this array to see which inputs is going to be checked
* Make a loop with categories (you have it)
* The save action should take all the values given and update it correctly with update_options

Hello - You'd like to see the code for $woo_categories?

global $woo_categories;
$woo_categories = array();
$woo_categories_args = array('hide_empty' => 0, 'builtin' => false);
$woo_categories_obj = get_categories($woo_categories_args);
foreach ($woo_categories_obj as $woo_cat) {
$woo_categories[$woo_cat->cat_ID] = $woo_cat->cat_name;}
$categories_tmp = array_unshift($woo_categories);

I don't have any issues displaying the categories or checking just one box. Can you help me with the code I posted before? What am I missing?

Hi - I appreciate any more help you can offer. Thanks!

I try:


array (
'name' => 'Categories',
'id' => 'jqs_select_categories',
'type' => 'checkbox',
'options' => $woo_categories,
),
);

else if ( isset ($_REQUEST['action']) && ( 'save' == $_REQUEST['action'] ) ){
if ( isset( $_REQUEST['myname'] ) ) {
update_option( 'jqs_select_categories', $_REQUEST['myname'] );
} else {
delete_option( 'jqs_select_categories' );
}
}


<h3><?php echo $value['name']; ?></h3>
<?php foreach ($value['options'] as $FPFoption) { ?>
<label for="<?php echo $FPFoption; ?>">
<input type="checkbox" name="myname[]" id="<?php echo $FPFoption; ?>" value="<?php echo $FPFoption; ?>"
<?php if ( get_option( $value['id'] ) == $FPFoption) { echo ' checked="checked"'; } ?> />
<?php echo $FPFoption; ?>
</label>


Louise comments:

Hello again - That didn't work. With this code, the "jqs_select_categories" does not show up in my wp-options table in the database. However, I can print out the results of "myname" successfully. The option is not making it to the database?

Francisco Javier Carazo Gil comments:

Insert a var_dump and a die() and tell me which is shown.



else if ( isset ($_REQUEST['action']) && ( 'save' == $_REQUEST['action'] ) ){

if ( isset( $_REQUEST['myname'] ) ) {

update_option( 'jqs_select_categories', $_REQUEST['myname'] );
var_dump( $_REQUEST['myname'] );
die();

} else {

delete_option( 'jqs_select_categories' );

}

}

Sure - Here is the output :

array(3) { [0]=> string(4) "Bath" [1]=> string(7) "Kitchen" [2]=> string(5) "Patio" }


My categories correctly displayed and then I selected 3 checkboxes - Bath, Kitchen & Patio.

Also, it now display in the database - a:3:{i:0;s:9:"Going Out";i:1;s:7:"Kitchen";i:2;s:5...

Francisco Javier Carazo Gil comments:

Ok, perfect, so now you have to do a checked function here:


<h3><?php echo $value['name']; ?></h3>

<?php $categories = get_option("your_categories"); // set the good name ?>

<?php foreach ($value['options'] as $FPFoption) { ?>

<label for="<?php echo $FPFoption; ?>">

<input type="checkbox" name="myname[]" id="<?php echo $FPFoption; ?>" value="<?php echo $FPFoption; ?> <?php if(in_array($FPFoption, $categories)) echo 'checked'; ?>"

<?php echo $FPFoption; ?>

</label>

Almost there, thank you!! !!!

-My message on "save" no longer displays - i.e. "Plugin Settings Saved."

-Also, If I want to call this option later, though, I am still not sure how to use get_option?

Francisco Javier Carazo Gil comments:

Perfect :)

Inline:

-My message on "save" no longer displays - i.e. "Plugin Settings Saved."
You can do the echo after update_option:
echo '<div id="message" class="updated fade"><p>Plugins settings saved'</p>

-Also, If I want to call this option later, though, I am still not sure how to use get_option?
You will have (you can use it wherever you want in your code):

$categories = get_option("option_name");

You will have an array and you could access it in the standard way $categories[0], $categories[1]...
