Requires that attribute id be set to the name of a script variable for later use by the true or false tags.

Valid comparison operators for integers are == (equal), != (not equal), >= (greater than or equal), <= (less than or equal), < (less than), and > (greater than).

Valid comparison operators for strings include all those for an integer plus |= (first string is a prefix of second string), |! (first string is not a prefix of second string), =| (first string is a suffix of second string), and !| (first string is not a suffix of second string).

When comparing strings that might include white space, use the forward slash \ at the start and end of the string.

The values being compared must be separated from the comparison operator by white space.

Any JSP tags embedded in the body of the eval tag are processed before the comparison is made.

The true and false tags are used to take action based on the result of the eval comparison.

Examples:

Compare the number of forums to 0.

 <jf:eval id="num_forums">
 <jsp:getProperty name="req" property="numberOfForums"/> == 0
 </jf:eval>
 

 <jf:eval id="sub">
 \Re: \ |= \<jsp:getProperty name="cm" property="subject"/>\
 </jf:eval>
 

 <name>eval</name>

 <info>Compares two values, use the true and false tags to test result of eval.

Optional attribute begin can be set to the number at which the forum_loop should start.

Optional attribute end can be set to the number at which the forum_loop should end.

Optional attribute match can be set to the id of a match tag to select only those forums that match the forum extended properties specified by the match tag.

During each loop the body of the forum_loop tag is processed.

The on_entry tag can be used to include content if this is the first time through the loop.

The on_exit tag can be used to include content if this is the last time through the loop.

The forum_loop continues looping until there are no more forums or the users items_per_page limit has been reached.

Uses the following HTTP input parameters

• login - indicates user is submitting the login form
• username - Yazd user name (userid) to login
• password - users password

Uses the users display preferences messageDepth, threadDepth, and itemsPerPage to determine which messages to display, how to display them, and how many messages to view on a page before triggering paging.

The is_parent, is_message, is_summary, is_total, next_page, and prev_page tags can be used to control what formatted content is generated based on user display preferences.
