    In my jquery code I have:

    $("#show").append("<img src=" +attachment.url+" alt="+attachment.alt+" title="+attachment.title+" description="+attachment.caption+" class='img-responsive img-thumbnail'/><input type='hidden' name='my_image_URL[]' value="+attachment.url+"></span>");

    My jquery code adds fields for news selected images and fills inputs names my_image_URL[]

    But this part of code PHP does not fill the input:

    if ( isset( $_POST['my_image_URL'] ) ) {

        $urls = $_POST['my_image_URL'];
             echo '<input name="imagens_home" value="'.$json_encode($urls).'" />';

        }

    Complete code:

    options.php

     register_setting(
            'tema-setting-group',//string $option_group
            'imagens_home' //string $option_name
            //calback $sanitize_calback      
        );

---
    add_settings_field(
         'home-imagens-top',//string $id
         'Imagens',//String $title
         'tema_home_imgs',//string $calback
         'opcoes_do_tema',//string $page    
         'tema-home-options'//string $section
         //string $args          
         );

//calback
function tema_home_imgs(){   
        $urlsImagens = esc_attr( get_option( 'imagens_home' ) ); // RETURN DB DATA

        include( get_template_directory() . '/inc/templates/selecao_imagens.php');

        if ( isset( $_POST['my_image_URL'] ) ) {

        $urls = $_POST['my_image_URL'];
             echo '<input name="imagens_home" value="'.$json_encode($urls).'" style="width:300px"/>';

        }   
    }

    selecao_imagens.php

    <input id="my_upl_button" type="button" value="Escolher Imagens" /><br/>

    <div class="row">
            <div id="exibe" class="sortable">       

            <?php           
            $urls = json_decode($urlsImagens, true);
                if ($urls != '' ) {
                foreach ($urls as $url) { 
             ?>          
                    <img src="<?php echo $url;?>"  class="img-responsive img-thumbnail " />
                    <input name="my_image_URL[]" value="<?php echo $url;?>"/>

            <?php
                 };
                }
            ?>
    </div>
    </div>

    theme_options.php

    `<?php settings_errors();?>

    <form method=”post” action=”options.php”>
    <?php settings_fields (‘tema-setting-group’); ?>

    <?php do_settings_sections (
    ‘opcoes_do_tema’//string $page

    ); ?>

    <?php submit_button ();

    ?>

    </form>`

    Apparently, this is all ok, but I do not know where the error is.

    After the submit the field becomes empty, print_r and var_drump return empty

    Thanks

    This line:

    echo '<input name="imagens_home" value="'.$json_encode($urls).'" />';

    has two problems. First, $json_encode should be json_encode. And second, a JSON-encoded string contains double-quotes which will break your HTML. The line should look something like this:

    
echo '<input name="imagens_home" value="' . htmlspecialchars(json_encode($urls)) . '" />';

    You should also review the options parameter for json_encode():

    Thanks DionDesigns

    I tried according to your suggestion, but it is not yet filling in the input.

    I also tried:

    If (isset ($ _POST ['my_image_URL'])) {
 Print_r ($ _ POST ['my_image_URL']);

}

    But after the submit does not appear anything on the screen, in the form correctly saves all other inputs except what I am trying to save the array, if I put some manual information goes ok. But I do not understand why it is not capturing the my_image_URL [] names of each image input. The action in form is like this:

    <Form method = “post” action = “options.php”>

    I’m using the Settings API

    I see the following line in your second block of code:

    $urls = json_decode($urlsImagens, true);

    Where is the $urlsImagens variable being defined?

    In any case, I’d suggest that you check your PHP error log to see if you have any other issues.

    Yes the variable exists it is defined.

    Isset works when I created a metabox with the following code in action:

    add_action( 'save_post', function ( $post_id ) {
	if ( isset( $_POST['my_image_URL'] ) ) { 
	    delete_post_meta( $post_id, 'my-image-for-post' ); 
		$urls = $_POST['my_image_URL'];		
		add_post_meta( $post_id, 'my-image-for-post', $urls );	
	}
});

    But now I’m trying to use the options in my theme, for the home page, using settings API:

    //calback
function tema_home_imgs(){   
        $urlsImagens = esc_attr( get_option( 'imagens_home' ) ); // RETURN DB DATA

        include( get_template_directory() . '/inc/templates/selecao_imagens.php');

        if ( isset( $_POST['my_image_URL'] ) ) {

        $urls = $_POST['my_image_URL'];
             echo '<input name="imagens_home" value="' . htmlspecialchars(json_encode($urls)) . '" />';
        }   
    }

    If I put print_r ($urls); Returns empty

    Yes exists it is defined.

		$urls = $_POST['my_image_URL'];		
		add_post_meta( $post_id, 'my-image-for-post', $urls );	
	}
});

    For the home page, options of my theme I´m using settings API:

    //calback
function tema_home_imgs(){   
        $urlsImagens = esc_attr( get_option( 'imagens_home' ) ); // RETURN DB DATA

        include( get_template_directory() . '/inc/templates/selecao_imagens.php');

        $urls = $_POST['my_image_URL'];
             echo '<input name="imagens_home" value="' . htmlspecialchars(json_encode($urls)) . '" />';
        }   
    }

    print_r ($urls); or var_dump($urls); Returns empty
