Getting If/elseif/else statements to work with assigned variables

I’m having the following problem with code (shown below) where I am trying to run an if/elseif/else statement to load a specific weblog based on what day it currently is. It will currently assign the first variable shown (monday) but will ignore any other content inserted within it.

{assign_variable:thedate="{current_time format="%D"}"}
   
        {if thedate == "Mon"}
                {assign_variable:my_weblog="monday"}
        {if:elseif thedate == "Tue"}
            {assign_variable:my_weblog="tuesday"}
        {if:elseif thedate == "Wed"}
        {assign_variable:my_weblog="wednesday"}
        {if:elseif thedate == "Thu"}
        {assign_variable:my_weblog="thursday"}
        {if:elseif thedate == "Fri"}
        {assign_variable:my_weblog="friday"}         
        {if:else}
        {assign_variable:my_weblog="friday"}              
        {/if}

You cannot use asigned variables dynamically like that. They are only assigned once, and cannot be later changed at run time. In PHP terms, they behave a lot like constants. Makes sense?

Ok that makes sense, now is there a dynamic variable or different approach I would want to take to accomplish the intent of the code?

Skip the assignment of an intermediary variable, like so:
```
{assign_variable:my_weblog="{current_time format="%l"}"}
```
You get the idea. Or use PHP 😊

would it be possible to assign it a value inside php?

ie:
```
<?php
$date="monday";
{assign_variable:my_weblog=$date};
?>
```
I’m aware this specific code will not work, but is there a method to accomplish that that would?

Thanks again.

No, that wouldn’t work. What are you trying to accomplish, ultimately?

Running conditions that would establish what the global variable would be, and then set it as a constant.

just to verify, my hope is that there is some way to have

it check if it is mon-fri, and assign that blog as the global variable.
if it is sat-sun. It will load friday.

Why not just use PHP in the input stage for this?

Would it be possible to get an example of that? I have been trying to do just that, but despite it running and giving the right code, it will not execute. I’ve tried a few variations, but this is the latest just to give you an example of my own:

<?php
         $date=date("D");
            
        if ($date == "Mon"){
             $globalvarblog="{assign_variable:my_weblog="monday"}";
              }
        else if ($date == "Tue"){
                     $globalvarblog="{assign_variable:my_weblog="tuesday"}";
              }
        else if ($date == "Wed"){
             $globalvarblog="{assign_variable:my_weblog="wednesday"}";
            }
        else if ($date == "Thu"){ 
             $globalvarblog="{assign_variable:my_weblog="thursday"}";
            }
        else if ($date == "Fri"){
             $globalvarblog="{assign_variable:my_weblog="friday"}";
            }
        else{
             $globalvarblog="{assign_variable:my_weblog="friday"}";        
            }

        echo "$globalvarblog";
        ?>

Hm, how about

<?php
$date = date("D");

if($date == 'Mon')
{
    $weblog_name = 'monday';
}
else
{
    $weblog_name = 'other-day';
}
?>

{exp:weblog:entries weblog="<?php echo($weblog_name);?>"}
...
{/exp}

PHP set to input. Shouldn’t this work?

Thank you, that did the trick, i was missing setting php parsing to input in preferences.
