WordPress - Overwriting a template plugin Shortcode - wordpress

Question

I'm new to php and wordpress.
When I edit an icon box from the theme in the admin panel, i have a few fields, like "title" and "content". The title is inside <h4> </h4> and content is inside <p>
</p>
I need to add another <p style='iconbox_price'></p> after the content, so i can edit it in the admin panel.
This is the code for the iconbox. How can i add this to it, so it would work out.
<?php
function easyweb_webnus_iconbox( $attributes, $content = null ) {
extract(shortcode_atts(array(
"type"=>'',
'icon_title'=>'',
'icon_link_url'=>'',
'icon_link_text'=>'',
"icon_name"=>'',
"iconbox_content"=>'',
"icon_size"=>'',
"icon_color"=>'',
"title_color"=>'',
"content_color"=>'',
"link_color"=>'',
"icon_image"=>'',
"featured"=>'',
"border_left"=>'',
"border_right"=>'',
), $attributes));
ob_start();
$type = ( $type == 0 ) ? '' : $type ;
$iconbox_style = $type17_start_wrap = $type17_end_wrap = '';
if ( $type==17 ) {
$iconbox_style = ( !empty($icon_color) ) ? ' style="color: ' . esc_attr($icon_color) . '"' : '' ;
$type17_start_wrap = '<div class="icon-wrap" style="background-color:' . esc_attr($icon_color) . '">';
$type17_end_wrap = '</div>';
}
$iconbox22_class = '';
if ( $type == 22 ) {
$iconbox22_class .= $featured ? ' ' . $featured : '';
$iconbox22_class .= $border_left ? ' ' . $border_left : '';
$iconbox22_class .= $border_right ? ' ' . $border_right : '';
}
echo '<article class="icon-box' . $type . $iconbox22_class . '" ' . $iconbox_style . '>';
if(!empty($icon_name) && $icon_name != 'none') :
if(!empty($icon_link_url))
echo '' . $type17_start_wrap . '' . do_shortcode( "[icon name='$icon_name' size='$icon_size' color='$icon_color']" ).'' . $type17_end_wrap . '';
else
echo $type17_start_wrap . do_shortcode( "[icon name='$icon_name' size='$icon_size' color='$icon_color']" ) . $type17_end_wrap;
elseif(!empty($icon_image)) :
if(is_numeric($icon_image)){
$icon_image = wp_get_attachment_url( $icon_image );
}
if(!empty($icon_link_url))
echo "<a href='$icon_link_url'>" . '<img src="'.$icon_image.'" alt="" />' . '</a>' ;
else
echo '<img src="'.$icon_image.'" alt="" />';
endif;
$title_style = !empty($title_color)?' style="color:'.$title_color.'"':'';
echo '<h4'.$title_style.'>' . $icon_title . '</h4>';
$content_style = !empty($content_color)?' style="color:'.$content_color.'"':'';
echo '<p'.$content_style.'>'.$iconbox_content .'</p>' ;
$link_style = !empty($link_color)?' style="color:'.$link_color.'"':'';
echo (!empty($icon_link_url) && (!empty($icon_link_text)) )?"<a".$link_style." class=\"magicmore\" href=\"{$icon_link_url}\">{$icon_link_text}</a>":'';
echo '</article>';
$out = ob_get_contents();
ob_end_clean();
$out = str_replace('<p></p>','',$out);
return $out;
}
add_shortcode('iconbox', 'easyweb_webnus_iconbox');
In html this is the code, that is generated:
<article class="icon-box14">
<a href="/razrabotka-saitov/">
<i class="sl-screen-desktop" style=" font-size:42px;"></i>
</a>
<h4 style="height: 22px;">Title</h4>
<p style="height: 116px;">Content<br></p>
<a class="magicmore" href="#">More</a>
</article>

Answer 1

You see the line there:
echo '<p'.$content_style.'>'.$iconbox_content .'</p>' ;
You can add your custom paragraph to that line:
echo '<p'.$content_style.'>'.$iconbox_content .'</p>
<p style='iconbox_price'></p>' ;

Answer 2

I found the solution in my case. Maybe it will help somebody else. I had to edit two files. In my case this is where the first file was located.
wp-content/plugins/'theme'-shortcodes/shortcodes/iconbox.php
I tried to look for where comes the variable $iconbox_content and found it in getting extracted in the code above from an array at this point:
extract(shortcode_atts(array(
"type"=>'',
'icon_title'=>'',
'icon_link_url'=>'',
'icon_link_text'=>'',
"icon_name"=>'',
"iconbox_content"=>'',
"icon_size"=>'',
"icon_color"=>'',
"title_color"=>'',
"content_color"=>'',
"link_color"=>'',
"icon_image"=>'',
"featured"=>'',
"border_left"=>'',
"border_right"=>'',
), $attributes));
So i searched through all the wordpress directory files, because i did not even have an idea where can i find it.
And found it in the themes => 'my theme' => 'my theme' => visualcomposer => shortcodes directory as 03-iconbox.php
I had there different arrays such as this:
array(
"type"=>'textarea',
"heading"=>esc_html__('Content', 'ew'),
"param_name"=> "iconbox_content",
"value"=>"",
"description" => esc_html__( "IconBox Content Goes Here", 'ew')
),
So i guess, the other half of what i did is very logical already, but here it is anyway:
I added an array in this file:
array(
"type"=>'textarea',
"heading"=>esc_html__('Price', 'ew'),
"param_name"=> "iconbox_price",
"value"=>"",
"description" => esc_html__( "Price goes here", 'ew')
),
And in the first file:
To extract "iconbox_price" =>'',
And lower: echo '<p class="iconbox_price">'.$iconbox_price .'</p>' ;
Wish that this helps someone!
