Wordpress是页面str替换

Question

I have page on wordpress site

http://upsourcemobileservices.com/solutions/

in footer.php I have added the following:

if(is_page('solutions')){
    echo str_replace("The MVNi","The MVNi solution was created to ensure that wireless communications are available to the smaller Telco operators.","The MVNi");
}

but it is not changing the contents of the page.

To my knowledge, Syntax is correct str_replace(find,replace,string)

What am I doing wrong?

I also tried using jQuery

function replaceText(jQuery) {
    $(".portfolio-thumbnail-content:nth-child(1)").replaceWith("<div class='portfolio-thumbnail-content'>The MVNi solution was created to ensure that wireless communications are available to the smaller Telco operators.</div>");
    $(".portfolio-thumbnail-content:nth-child(2)").replaceWith("<div class='portfolio-thumbnail-content'>Primarily aimed at existing Telcos our MVNc solution integrates your existing platforms with ours through the use of APIs.</div>");
    $(".portfolio-thumbnail-content:nth-child(3)").replaceWith("<div class='portfolio-thumbnail-content'>UMS turnkey solution is a complete MVNO in a box.</div>");
    $(".portfolio-thumbnail-content:nth-child(4)").replaceWith("<div class='portfolio-thumbnail-content'>This solution allows you to select the products and services that you want and integrate them with your existing platforms.</div>");
}
$(document).ready(replaceText);

but can't seem to get that working either, here's a fiddle http://jsfiddle.net/vzy9R/3/

Answer 1

I used jQuery eq() selector to find elements containing class portfolio-thumbnail-content and then using .replaceWith() I was able to load my teaser content (excerpts) ending with complete sentences.

For example, the About page:

(function ($) {
 $(".portfolio-thumbnail-content:eq(0)").replaceWith("<div class='portfolio-thumbail-content'>This is my new complete sentence teaser for Team.</div>");
 $(".portfolio-thumbnail-content:eq(1)").replaceWith("<div class='portfolio-thumbail-content'>This is my new complete sentence teaser for Partners.</div>");
})(jQuery);

Then I had to figure out a way to implement those scripts into the body of those pages, so I wrote my own shortcodes and added them to functions.php

//[replaceTextAbout]
 function replaceTextAbout_func( $atts ){
  return "<script src='/javascript/custom/replaceText-About.js'></script>";
 }
 add_shortcode( 'replaceTextAbout', 'replaceTextAbout_func' );
