Weaving Dream dedecms Home page How to invoke the content of a single document

Many friends who use the DEDECMS single-page document feature want to know how to call the content of a single-page document in the home of the dream, the following to teach you the specific implementation method:

The steps are as follows:

First, insert the following code where the first page template needs to display the contents of a single document:

{dede:sql sql= "select Body from ' dede_sgpage ' where aid = 3"function= "Htmlspecialchars (Cn_substr (@me , ()) "/] {/dede:sql}

The body of the sql= "select Body" inside the code is a single-page document content;

From ' Dede_sgpage ' here dede_sgpage is a single page document archive data table, the default is the prefix is dede_, if your database prefix modified, please fill in their own;

Where aid = 3 "AID = 3 here is the ID of our single-page document, and we need to invoke the content of the single-page document, and replace this with the ID of the document in which it is located!"

[Field:body function= "Htmlspecialchars (Cn_substr (@me, 100))"/]

Field:body the body here is also the content of a single page document;

(Cn_substr (@me, 100) Here's 100 is the number of words we are prepared to display, which can be adjusted.

Doing so will find that there is a problem with the HTML tag being called out. We need to filter it out, so we can use the following code:

{dede:sql sql= "select Body from ' dede_sgpage ' where aid = 3"function= "Htmlspecialchars (CN_SUBSTR ( Html2text (@me), (+)) "/] {/dede:sql}

Html2text () This function is the code that removes the HTML tag;

Cn_substr (str,100) This function is to intercept the string length.

This allows us to invoke the contents of a single-page document.
