4. Get column address function through ID
Syntax: sys_ReturnBqClassname($r,9)
Note: $r is an array containing column IDs, and the variable name can be named arbitrarily.
Usage example: Get the column address with column ID=2.
<?php
$cr['classid']=2;
$classurl=sys_ReturnBqClassname($cr,9);
echo $classurl;
?>
Other ways to get the column address through ID:
(1),/e/public/ClassUrl/?Column ID
(2), /<?=$class_r column ID?>

5. Obtain information content page address function
Syntax: sys_ReturnBqTitleLink($r)
Note: $r is an array containing the contents of the "id, classid, newspath, filename, groupid, titleurl" fields. The variable name can be named arbitrarily.
Usage example: Get the news page address of information ID=8
<?php
$nr=$empire->fetch1("select id,classid,newspath,filename,groupid,titleurl from {$dbtbpre}ecms_news where id='8' limit 1");
$titleurl=sys_ReturnBqTitleLink($nr);
echo $titleurl;
?>
Other ways to obtain the information content page address through ID:
/e/public/InfoUrl/?classid=Column ID&id=Information ID
6. Prompt information function 1
Syntax: printerror($error,$gotourl,$ecms,$noautourl,$novar)
Description:
$error: Prompt information content, which can be a language pack variable or direct prompt content.
$gotourl: Prompt information redirection link address
$ecms: 0 is background prompt information, 1 is foreground prompt information, 8 is background prompt information (alert mode), 9 is foreground prompt information (alert mode)
$noautourl: 0 means automatic redirection to the page, 1 means no automatic redirection to the page. This parameter can be omitted and defaults to 0
$novar: 0 means that the prompt information content adopts the language package variable, 1 means that the prompt information content is the direct prompt content. This parameter can be omitted and defaults to 0
Usage example:
printerror('DbError','http://www.phome.net',1), front desk prompt, the content of the prompt information is the content of the language package DbError variable, redirect to the imperial website
printerror('database error','http://www.phome.net',1,0,1), the front desk prompts, the prompt message content is "database error", redirect to the imperial website
Additional notes:
This function needs to be combined with the $editor variable to determine the directory level. The default $editor variable is 0.
When the program file is in the /e/path/ directory, $editor does not need to be set, that is, the default is 0.
When the program file is in the /e/path/path2/ directory, $editor=1.
When the program file is in the /e/path/path2/path3/ directory, $editor=2.
When the program file is in the /e/path/path2/path3/path4/ directory, $editor=3.
7. Prompt information function 2 (direct prompt content)
Syntax: printerror2($error,$gotourl,$ecms,$noautourl)
Description:
$error: The content of the direct prompt information.
$gotourl: Prompt information redirection link address
$ecms: 0 is the default prompt information mode, 9 is the pop-up prompt information mode (alert mode). This parameter can be omitted and defaults to 0
$noautourl: 0 means automatic redirection to the page, 1 means no automatic redirection to the page. This parameter can be omitted and defaults to 0
Usage example:
printerror2('Added completed','http://www.phome.net'), the prompt message content is "Added completed", redirect to the imperial website
Additional notes:
This function does not need to be combined with other variables and can be used at any directory level. Using language pack variables is not supported.
8. Set the system COOKIE variable function
Syntax: esetcookie($var,$val,$life,$ecms)
Description:
$var: is the variable name
$val: is the variable value
$life: is the COOKIE validity time, in seconds, 0 means not to save. This parameter can be omitted, and the default is not to save.
$ecms: 0 is to set the foreground COOKIE variable, 1 is to set the background COOKIE variable. This parameter can be omitted and defaults to 0.
Usage example:
esetcookie('mybody','Empire'), defines the front-end "COOKIE prefix + mybody" variable, and the variable content is "Empire"
esetcookie('mybody','Empire',0,1), defines the background "COOKIE prefix + mybody" variable, and the variable content is "Empire"
Additional notes:
This set COOKIE function will add the COOKIE prefix to the variable name. You can also directly use PHP's own setcookie to define it.
9. Obtain the system COOKIE variable function
Syntax: getcvar($var,$ecms)
Description:
$var: is the variable name
$ecms: 0 is to set the foreground COOKIE variable, 1 is to set the background COOKIE variable. This parameter can be omitted and defaults to 0.
Usage example:
getcvar('mlusername'), get the username of the member who logged in at the front desk
