smarty + php - Conditional page break ...

[southbeach]

Hope this is the correct forum for this question ...

Using smarty template engine, I am trying to conditionally add a page break

				{assign var="left_line_count" value="`$left_line_count`+1" }
				{ if $left_line_count > $max_lines_page }
					<p class="break">Page Break!</p>
					{assign var="left_line_count" value="18" }
				{ /if }

This snippet appears under each row tab

<tr> blah blah blah </tr>

The CSS I am using is

p.break { page-break-after: always; }

I do not see the string "Page Break" on the rendered page nor I get a page break if I print the document. This tells me that there is something wrong with my logic and/or syntax.

Can you offer some advise?

Thanks!

i am not familiar with the smarty language constructs. i thought it was based on php but seeing your script i am not confident that this is right. php knows nothing, for example, of constructs like assign. and if conditionals must be encapsulated in brackets.

but going back to first principles, there is nothing intrinsically wrong with your html and css. the css may be disapplied due to more granular rules being applied but more likely is that your conditional is not being fired. does the code work if you remove the conditional?

and does this work?

value="`$left_line_count`+1"

would this not simply assign the value "5+1" in each case? i.e. the string form. not knowing smarty i am not sure. perhaps this would work

{assign var="left_line_count" value=$left_line_count+1}
{ if $left_line_count > $max_lines_page }
<p class="break">Page Break!</p>
{assign var="left_line_count" value="18" }
{ /if }

i read in the smarty manual that the correct syntax for increment is as follows

{assign var="left_line_count" value=[red]`[/red]$left_line_count+1[red]`[/red]}

jpadie,

Thanks for your assistance! Here is the code I ended up with

					{ math equation="x + 1" x=$left_line_count assign="left_line_count" }
					{ if $left_line_count > $max_lines_page }
						<p class="break">&nbsp;</p>
						{assign var="left_line_count" value="18" }
					{ /if }

After further investigation, I found that the template used in this project is "templatelite", a flavor derived from "smarty" ...

Regards,


Jose
