Need help with a conditional statement

Question

I am trying to control what is displayed in a table view based on a conditional.

Here is the code I am trying to use:

<tr class="odd">
    <td>Small</td>
    <td>1000x600</td>
    <td>$25</td>
</tr>
<tr class="even">
    <td>Medium</td>
    <td>2000 x 1300</td>
    <td>$50</td>
</tr>
{if max_dimensions != '1536 x 2048' OR max_dimensions != '2048 x 1536' }
<tr class="odd">
    <td>Large</td>
    <td>3000 x 2003</td>
    <td>$75</td>
</tr>
{/if}

In this case if the max_dimensions of a photograph is not '1536 x 2048' or '2048 x 1536' I want the third row of data to be displayed.

I limited it to just one conditional as follows and it worked. However when I add the OR, it fails.

{if max_dimensions != '1536 x 2048' }
<tr class="odd">
    <td>Large</td>
    <td>3000 x 2003</td>
    <td>$75</td>
</tr>
{/if}

That basic objective is, if the picture is not big enough, I don't want the third row to be displayed. What is the correct way to word this?

Thanks.

Answer 1

You can't really use an OR conditional when both are "not equal to" because both conditions can be satisfied at the same time (as in your example, when the entry in question matches both conditions at the same time). You can easily use OR when you are asked for equal to, but not equal to is a different animal. On the surface it seems like OR is what you're looking for, but really what it seems you're looking for is this:

{if max_dimensions != "option A" OR "option B"}
    display third row only if max dimensions are anything other than options A or B
{/if}

But that's not how such a conditional is written - but that's the structure of the logic you are going for. But to write that, you use:

{if max_dimensions != "option A" AND max_dimensions != "option B"}
    display third row only if max dimensions are anything other than options A or B
{/if}

By using AND you are saying you want the third row to display whenever options A and B are not the value. By using OR, you're saying you want the third row if option A is not the value or option B is not the value - two conditions rather than one, which buggers up the logic a bit.

Make sense?

Can you try it:

{if "{max_dimensions}" != "1536 x 2048" OR "{max_dimensions}" != "2048 x 1536"}
<tr class="odd">
    <td>Large</td>
    <td>3000 x 2003</td>
    <td>$75</td>
</tr>
{/if}

If it didn't work, you can try another quick way:

    {if "{max_dimensions}" != "1536 x 2048"}
    <tr class="odd">
        <td>Large</td>
        <td>3000 x 2003</td>
        <td>$75</td>
    </tr>
    {if:elseif "{max_dimensions}" != "2048 x 1536"}
    <tr class="odd">
        <td>Large</td>
        <td>3000 x 2003</td>
        <td>$75</td>
    </tr>
{if:else} {/if}
