IF condition not working on home

[badboy]

If a listing has an image it is displayed. If not then a default image is shown

I got this by adding the following code in details_link.html

<%if $content%>
<img src="<%$site_url%>/thumbs/<%$logo%>.jpg" /></a>

<%else%>

<img src="/images/nologo.jpg" /></a>
<%/if%>

Because i wanted the same on my home i added the following code in
block_random_listing_rows.html

<%if $content%>
<img src="<%$site_url%>/thumbs/<%$logo%>.jpg" /></a>

<%else%>

<img src="/images/nologo.jpg" /></a>
<%/if%>

Then i tried it with

<%if $logo%>
<img src="<%$site_url%>/thumbs/<%$logo%>.jpg" /></a>

<%else%>

<img src="/images/nologo.jpg" /></a>
<%/if%>

Then i tried it with another db field called logo2(with the name of the image)

<%if $logo%>
<img src="<%$site_url%>/thumbs/<%$logo%>.jpg" /></a>

<%elseif $logo2%>

<img src="/images/nologo.jpg" /></a>
<%/if%>

But nothing works. Why does it work in on the detail page, and not on the homepage?

Because the variable in question is not available on index.php, only on detail.php

Wow fast reply. Thank you.

But how does i make it work on index.php.

Which variable to use it on index.php?

I hope you can help me.

To make it work you'd need to carry over the variables and any associated code in the .php file(s).

Hi Bruce,

Can you show me an example. Let's start with the detail page.

In the detail_link.html i use this code:
<%if $logo%>
<img src="<%$site_url%>/thumbs/<%$logo%>.jpg" /></a>

<%else%>

<img src="/images/nologo.jpg" /></a>
<%/if%>

so in detail.php i must add ?

if (!empty($logo)) {
$logo= "<img src="/thumbs/$logo>.jpg" />";
}
else {
$logo= "<img src="/thumbs/nologo.jpg" />";
}

You don't use if statements in the .php files. That will only cause issues.

// vars global configuration
global $dbConn, $theme_path, $number_of_links_format, $category_separator,
$cat_default_image, $cat_columns, $max_sub_cat, $cat_link_style,
$subcat_link_style, $cat_table_width, $cat_cellspacing,
$theme_name, $cat_description_format;

You would need to add the variable you want to that list, plus add any code onto index.php to make that variable work.

This is something you're going to have to figure out on your own, I'm not a programmer and custom programming isn't part of support.

There are examples on the forum from other users however, perhaps that can help you. Or if you'd like you can email custom [at] nicecoder.com and we can get you a quote to do this.
