I would like to customize the meta tags on the product pages. I've added a table to the database that includes custom product descriptions (as per http://www.pricetapestry.com/node/1278) as well as extra fields for meta-title, meta-keywords, and meta-description.
The custom product descriptions appear fine with the revised code for product.php, but what code is needed and what file needs to be edited for the custom meta tags to appear in the header?
Thanks.
The table i'm using is not part of the original set. I've created a new table called "description" containing the custom information. From the html/product.php file, the code for the custom on-page title and description is below. I think I need some similar code for the header in the products.php file?
<?php
$desc_sql = "SELECT name FROM `".$config_databaseTablePrefix."description` WHERE sku='".$mainProduct["name"]."'";
if (database_querySelect($desc_sql,$desc_rows))
{
print $desc_rows[0]["name"];
}
else
{
print $mainProduct["name"];
}
?>
<?php
$desc_sql = "SELECT description FROM `".$config_databaseTablePrefix."description` WHERE sku='".$mainProduct["name"]."'";
if (database_querySelect($desc_sql,$desc_rows))
{
print $desc_rows[0]["description"];
}
else
{
print $mainProduct["description"];
}
?>
Hi,
Ah - in that case have a go with something like this;
$sql = "SELECT meta-title,meta-description,meta-keywords FROM `".$config_databaseTablePrefix."description` WHERE sku='".$product["products"][0]["name"]."'";
database_querySelect($sql,$rows);
$header["title"] = htmlentities($rows[0]["meta-title"],ENT_QUOTES,$config_charset);
$header["meta"]["description"] = htmlentities($rows[0]["meta-description"],ENT_QUOTES,$config_charset);
$header["meta"]["keywords"] = htmlentities($rows[0]["meta-keywords"],ENT_QUOTES,$config_charset);Cheers,
David.
The following error ocurred...

Hi,
The first thing I noticed is that database_safe() should be in place...
$sql = "SELECT meta-title,meta-description,meta-keywords FROM `".$config_databaseTablePrefix."description` WHERE sku='".database_safe($product["products"][0]["name"])."'";...but other than that; can you double-check the field names? Are they exactly as shown, e.g. meta-title, meta-description, meta-keywords?
Cheers,
David.
Same error.
Yes, the table and field names look to be correct.
Table: description
fields: sku, name, description, meta-title, meta-keywords, meta-description
Hi,
The debug version of includes/database.php should reveal the actual error. Click here to download, extract and upload database.php to the /includes/ folder of your site - then when you run the script again the actual MySQL error message will be displayed which should indicate the problem...
Cheers,
David.
The error is:
[SELECT meta-title,meta-description,meta-keywords FROM `description` WHERE sku='51625A'][Unknown column 'meta' in 'field list']
Hi,
That sounds like the hyphen in the field name is breaking the structure, so back-ticks would be required. Have a go with:
$sql = "SELECT `meta-title`,`meta-description`,`meta-keywords` FROM `".$config_databaseTablePrefix."description` WHERE sku='".database_safe($product["products"][0]["name"])."'";Cheers,
David.
That works now, thanks!
One additional issue. How can I get the regular meta-tags to show if I don't have a record for a custom meta tag? Right now, it's just blank if the record doesn't exist.
Hi,
That's a simple case of using an IF statement on the value before using it; otherwise using the original code; so in place of:
$header["title"] = htmlentities($rows[0]["meta-title"],ENT_QUOTES,$config_charset);
$header["meta"]["description"] = htmlentities($rows[0]["meta-description"],ENT_QUOTES,$config_charset);
$header["meta"]["keywords"] = htmlentities($rows[0]["meta-keywords"],ENT_QUOTES,$config_charset);...use:
if ($rows[0]["meta-title"])
{
$header["title"] = htmlentities($rows[0]["meta-title"],ENT_QUOTES,$config_charset);
}
else
{
$header["title"] = htmlentities($q,ENT_QUOTES,$config_charset);
}
if ($rows[0]["meta-description"])
{
$header["meta"]["description"] = htmlentities($rows[0]["meta-description"],ENT_QUOTES,$config_charset);
}
else
{
$header["meta"]["description"] = translate("Price search results for")." ".htmlentities($q,ENT_QUOTES,$config_charset);
}
if ($rows[0]["meta-keywords"])
{
$header["meta"]["keywords"] = htmlentities($rows[0]["meta-keywords"],ENT_QUOTES,$config_charset);
}
else
{
$header["meta"]["keywords"] = htmlentities($q,ENT_QUOTES,$config_charset);
}Cheers,
David.
Hi david
trust you are well
was just wondering how would i go about including the main product category in the product page meta tags?

Hi Paul,
Sure - for example to add the category as a keyword look for the following line in products.php:
$header["meta"]["keywords"] = htmlentities($q,ENT_QUOTES,$config_charset);...and then immediately afterwards, add:
if ($rows[0]["category"])
{
$header["meta"]["keywords"] .= ",".htmlentities($rows[0]["category"],ENT_QUOTES,$config_charset);
}Cheers,
David.

Hi,
You'll find where the title and meta tags are set on lines 50/52/54 of products.php;
$header["title"] = htmlentities($q,ENT_QUOTES,$config_charset);$header["meta"]["description"] = translate("Price search results for")." ".htmlentities($q,ENT_QUOTES,$config_charset);
$header["meta"]["keywords"] = htmlentities($q,ENT_QUOTES,$config_charset);
...so to use fields from your database instead, use something like:
$header["title"] = htmlentities($product["products"][0]["meta-title"],ENT_QUOTES,$config_charset);$header["meta"]["description"] = htmlentities($product["products"][0]["meta-description"],ENT_QUOTES,$config_charset);
$header["meta"]["keywords"] = htmlentities($product["products"][0]["meta-keywords"],ENT_QUOTES,$config_charset);
(no newlines in the database field names of course, if you copy and paste the above block it should appear correctly!)
Hope this helps!
Cheers,
David.
