How does DEDECMS remove the last loop symbol? This problem may be often seen in our daily study or work. I hope you can gain a lot from this question. The following is the reference content that the editor brings to you, let's take a look at it!

How does DEDECMS remove the last loop symbol?

The DEDECMS tag loop calls the code that removes the last loop symbol, which can be referred to by friends who need it.

Dream-weaving tags allow limited programming extensions.

The format is:

{dede:tagname runphp='yes'} $aaa = @ me; @ me = "123456"; {/ dede:tagname}

@ me represents the value of the tag itself, so in-tag programming cannot use statements like echo, and can only pass all return values to @ me.

In addition, because the program code takes up the contents of the underlying template InnerText, the tags that need to be programmed can only use the default InnerText.

Of course, we have [field:global name=autoindex/] here, but we can program in the following ways:

[field:global name=autoindex] $aaa = @ me; @ me= "123456"; [/ field:global]

All we need here is a judgment, the code is as follows:

[field:global name=autoindex runphp= "yes"] (@ meteorology 8)? @ me= "|": @ me= "; [/ field:global]

This means that the tag is empty when autoindex equals 8, otherwise it is "|".

Let's take a look at this code in general:

{dede:arclist row='8' att='3' type='p_w_picpath.'} [field:litpic/] [field:global name=autoindex runphp= "yes"] (@ meteor8)? @ me= "|": @ me= "; [/ field:global] {/ dede:arclist}

This generates the code in the form we want, and a lot of FLASH can be solved with this style.
