Question

I’m having trouble getting HTML::Template‘s <TMPL_IF> blocks to function — it seems like my template is just skipping that code entirely.

  <TMPL_LOOP NAME=DATA>
    <TMPL_VAR NAME=complete><br>
    <TMPL_IF NAME="complete">
                    <!-- Some HTML here -->
    <TMPLE_ELSE>
        <!-- Some other HTML here -->
    </TMPL_IF>
  </TMPL_LOOP>

The TMPL_VAR line is displaying the expected values, but nothing in the block below it is showing up whatsoever. The data structure I’m passing in to the template is:

    $VAR1 = [
      {
        'code' => 26,
        'message' => 'Start building sensors for Jarvis',
        'complete' => 0
      },
      {
        'code' => 33,
        'message' => 'Machine learning to determine if actions are appropriate or not',
        'complete' => 0
      },
      {
        'code' => 37,
        'message' => 'Play by genre audioserv method',
        'complete' => 0
      }
    ];

Any help is greatly appreciated — I’ve been banging my head against it for the last hour.

Answer 1

From the fine manual:

The <TMPL_IF> tag allows you to include or not include a block of the template based on the value of a given parameter name. If the parameter is given a value that is true for Perl – like ‘1’ – then the block is included in the output. If it is not defined, or given a false value – like ‘0’ – then it is skipped.

All your completes are zero so <TMPL_IF> won’t show anything. You might expect the “else” branch to be displayed but you don’t have any <TMPL_ELSE> branches, you have <TMPLE_ELSE>. Fix the typo and try again.
