 Posted: Mon Mar 26, 2012 6:56 pm Post subject: Inserting an {if} inside another {if} doesn't work |
 |
|
Hello all, I am trying to display two (2) field items into a page using the following code, but its not working... I don't know if it has anything to do with an {if} statement inside another... not sure if this is even possible
| Code: | {if $field->name == 'drawings'}
<div id="{$name}">Download DWG Drawing: <a href="{$entry->file_location}/{$field->value}">{$field->value}</a><br/></div>
{* * * PDF DRAWING * * *}
{if $field->name == 'pdf_drawing'}
<div id="{$name}">Download PDF Drawing: <a href="{$entry->file_location}/{$field->value}">{$field->value}</a></div>
{/if}
{/if}
any suggestions/ideas? Thank you :?: |

So I was able to solve this by passing just calling the parameter separately as someone had mention I could do (i.e. I am not a programmer, so I had a hard time figuring this one out). Here is my final working code. By the way, would you have done it differently? 
| Code: | {if $field->name == 'drawings'}
<div id="{$name}">
{* * * DWG DRAWING * * *}
<div id="dwgdra">Download DWG Drawing: <a href="{$entry->file_location}/{$field->value}">{$field->value}</a><br/></div>
{* * * PDF DRAWING * * *}
<div id="pdfdra">Download PDF Drawing: <a href="{$entry->file_location}/{$entry->fields.pdf_drawing->value}">{$entry->fields.pdf_drawing->value}</a></div>
</div>
{/if} |

I know that you've resolved this so that it works for you, but it may be helpful to explain why it didn't work before. The outer {if} is evaluating the $field->name value. If it's "drawings" then the stuff inside the {if} happens.
Then, from within that {if} you're evaluating $field->name again to see if it equals "pdf_drawing" which we already know to be false because the first {if} only triggers if $field->name is equal to "drawings."
If you're only wanting to display the one that exists (either a "drawing" or a "pdf_drawing") you'll need to do an {elseif} instead of a nested {if} like so:
| Code: | {if $field->name == 'drawings'}
<div id="{$name}">Download DWG Drawing: <a href="{$entry->file_location}/{$field->value}">{$field->value}</a><br/></div>
{* * * PDF DRAWING * * *}
{elseif $field->name == 'pdf_drawing'}
<div id="{$name}">Download PDF Drawing: <a href="{$entry->file_location}/{$field->value}">{$field->value}</a></div>
{/if} |

Thank you for explaining, I am not a programmer so I can't explain in too much detail what the process is, I was able to figure it out with the help of a developer on another forum.
Thank you for explaining the elseif alternative, I want to go back and try this so that I learn something new. Thanks again! |
