Confira aqui uma lista de scripts interessantes para ser usado no wordpress.<\/p>\n

1. Melhorar a qualidade da foto ao salvar<\/strong><\/p>\n

add_filter( 'jpeg_quality', create_function( '', 'return 100;' ) );<\/pre>\n
_______________________<\/p>\n
\u00a02. Melhorar a coloca\u00e7\u00e3o nas buscas do google<\/strong><\/p>\n
Esse script abaixo define muitas coisas direto no cabe\u00e7alho do site para melhoras as buscas.<\/p>\n
O que faz:<\/p>\n
    \n
  1. Vai gerar todas as categorias;<\/li>\n
  2. vai gerar todas as tags;<\/li>\n
  3. vai gerar a imagem do post;<\/li>\n
  4. quando for um post ou uma page, vai mostrar o titulo, um texto curto e uma imagem se tiver;<\/li>\n
  5. quando for a p\u00e1gina inicial, vai mostrar o t\u00edtulo geral do site, as categorias e as tags;<\/li>\n<\/ol>\n
    <?\r\n$metakeywords = '';\r\n$keywords = get_the_category( $post->ID ); foreach ( $keywords as $keyword ) {$metakeywords .= $keyword->cat_name . \", \";}\r\n$posttags = get_the_tags(); if ($posttags) { foreach($posttags as $tag) { $metakeywords .= $tag->name . ', '; } }\r\n\/\/imagem\r\n$image = wp_get_attachment_image_src( get_post_thumbnail_id(), 'medium' );\r\n$image = $image[0];\r\n?>\r\n<meta name=\"title\" content=\"<?php if ( is_single() ) { single_post_title('', true); } else {   bloginfo('name');  } ?>\" \/>\r\n<?php if (is_single() || is_page() ) : if (have_posts() ) : while (have_posts() ) : the_post(); ?>\r\n<meta name=\"description\" content=\"<?php echo get_the_excerpt();?>\">\r\n<?php endwhile; endif; elseif (is_home() ): ?>\r\n<meta name=\"description\" content=\"<?php bloginfo('description'); ?>\">\r\n<?php endif; ?>\r\n<meta name=\"Keywords\" content=\"<? echo $metakeywords; ?>\">\r\n<meta property=\"og:image\" content=\"<? echo $image; ?>\" \/>\r\n<link rel=\"image_src\" href=\"<? echo $image; ?>\" \/><\/pre>\n
     <\/p>\n
    _______________________<\/p>\n
    3. Adicionar um script no header e salve em functions.php<\/strong><\/p>\n
    function add_meta_tags() {\r\necho \"<script language='JavaScript'>document.onselectstart = function() {return false}<\/script>\";\r\n}<\/pre>\n
    Pode ser colocado qualquer script, nesse acima por exemplo.<\/p>\n
     <\/p>\n
    Nesse caso tirei as permiss\u00f5es de selecionar, pra copiar e colar meu conte\u00fado.<\/p>\n
    * chame esse script no header.<\/p>\n
    add_action('wp_head','add_meta_tags');<\/code><\/p>\n
     <\/p>\n
    Um script mais completo seria assim<\/p>\n
    function add_meta_tags() {\r\necho \"<script language='JavaScript'>document.onselectstart = function() {return false}<\/script>\";\r\n\/\/para adicionar imagem destacada post\r\nif(!has_post_thumbnail( $post->ID ) OR !is_singular()) {\r\n$image = \"https:\/\/www.agenciaempregoscuritiba.com.br\/wp-content\/uploads\/2015\/11\/aec_capa.png\";}\r\nelse{$image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'medium' );\r\n$image = $image[0];}\r\necho \"\r\n<meta property=\\\"og:image\\\" content=\\\"$image\\\" \/>\r\n<link rel=\\\"image_src\\\" href=\\\"$image\\\" \/>\r\n\";\r\n}\r\nadd_action('wp_head', 'add_meta_tags');<\/pre>\n
    Acima o que faz \u00e9:<\/p>\n
      \n
    1. Desabilito pra selecionar copiar colar;<\/li>\n
    2. Adiciono uma imagem aleat\u00f3ria no post ou p\u00e1gina se n\u00e3o tiver imagem ou se tiver imagem eu coloco a imagem principal da postagem ou p\u00e1gina;<\/li>\n<\/ol>\n

      4. Colocar um contador de visualiza\u00e7\u00f5es das postagens, direto em functions.php<\/strong><\/p>\n

' visualiza\u00e7\u00e3o(\u00f5es)';\t\r\n        }\r\n    }\r\n}\r\n<\/pre>\n
       <\/p>\n
      Continuando…<\/p>\n
      Se quiser filtrar pelos mais vistos, coloque direto no c\u00f3digo, em algum lugar, por exemplo em header.php<\/p>\n
      <ul>\r\n <?php $popularpost = new WP_Query( array( 'posts_per_page' => 5, 'meta_key' => '_post_views_count', 'orderby' => 'meta_value_num', 'order' => 'DESC' ) );\r\n while ( $popularpost->have_posts() ) : $popularpost->the_post();\r\n ?>\r\n <li>\r\n <small><?php the_category(', '); ?><\/small>\r\n <a href=\"<?php echo get_permalink(); ?>\" title=\"<?php the_title_attribute(); ?>\">\r\n <h3><?php the_title(); ?><h3>\r\n <\/li>\r\n <?php\r\n endwhile;\r\n wp_reset_query();\r\n ?>\r\n <\/ul><\/pre>\n
