Hi David,
I am trying to create an export to CSV of alle the unique products (based on "EAN").
It should contain; Name, brand, lowest price, image link (based on imagecache) and ofcourse a link.
Could you help me with this?
Best regards
Two additional questions:
-If i only would like to export product above (for example) €50,-, what should i add to the query?
-Can i make a cronjob for this script? (because it now downloads trough the browser)
Best regards
Hi Alex,
Sure - the run the following from scripts/ folder instead of top level, and it will create the export in the feeds/ folder as export_products.csv. For the minimum price restriction, see the HAVING clause in the SQL at line 7...
<?php
set_time_limit(0);
require("../includes/common.php");
$fp = fopen($config_feedDirectory."export_products.csv","w");
$link = mysqli_connect($config_databaseServer,$config_databaseUsername,$config_databasePassword,$config_databaseName);
mysqli_set_charset($link,"utf8");
$sql = "SELECT *,MIN(price) AS minPrice FROM `".$config_databaseTablePrefix."products` GROUP BY `ean` HAVING minPrice > '50.00'";
mysqli_real_query($link,$sql);
$result = mysqli_use_result($link);
fwrite($fp,"name,brand,price,imageLink,link\n");
if (isset($_SERVER["HTTP_HOST"]))
{
$baseHREF = "http".(isset($_SERVER["HTTPS"])&&$_SERVER["HTTPS"]?"s":"")."://".$_SERVER["HTTP_HOST"];
}
else
{
$baseHREF = "http://www.example.com";
}
while($row = mysqli_fetch_assoc($result))
{
$imageLink = $baseHREF.$config_baseHREF."imageCache.php?src=".base64_encode($row["image_url"]);
$link = $baseHREF.tapestry_productHREF($row);
fwrite($fp,$row["merchant"].",");
fwrite($fp,$row["name"].",");
fwrite($fp,$row["description"].",");
fwrite($fp,$row["image_url"].",");
fwrite($fp,$row["buy_url"].",");
fwrite($fp,$row["minPrice"].",");
fwrite($fp,$imageLink.",");
fwrite($fp,$link."\n");
}
fclose($fp);
?>
For the cronjob, use the same as your cron.php command line replacing cron.php with export.php e.g.
cd /path/to/scripts/;/usr/bin/php export.php
Or alternatively, if you would like it to run immediately after cron.php as part of the same job, use for example;
cd /path/to/scripts/;/usr/bin/php cron.php;/usr/bin/php export.php
That way you wouldn't have to worry about scheduling export.php to ensure that it is never running as the same time as the import process...
Cheers,
David.

Hi Alex,
Just a follow up to note that when executing from the command line (cronjob), the site URL cannot be derived by the script and must therefore be hardcoded; so in place of;
$baseHREF = "http".(isset($_SERVER["HTTPS"])&&$_SERVER["HTTPS"]?"s":"")."://".$_SERVER["HTTP_HOST"];...now:
if (isset($_SERVER))
{
$baseHREF = "http".(isset($_SERVER["HTTPS"])&&$_SERVER["HTTPS"]?"s":"")."://".$_SERVER["HTTP_HOST"];
}
else
{
$baseHREF = "http://www.example.com";
}(corrected above, edit "http://www.example.com" as required)
Cheers,
David.

Hi David,
have just tried the script trough Cron but i get errors:
{code saved}
Hello Alex,
Regarding the unset warning that would indicate that $_SERVER is set but not $_SERVER["HTTP_HOST"] so the isset() check can use that instead - that and file mode updated above...
Cheers,
David.

Hi David,
There was a file created but it was empty.
Hello Alex,
Sure - have a go with something like this, saved as for example export.php (top level)
<?phpset_time_limit(0);
require("includes/common.php");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=products.csv");
$link = mysqli_connect($config_databaseServer,$config_databaseUsername,$config_databasePassword,$config_databaseName);
mysqli_set_charset($link,"utf8");
$sql = "SELECT *,MIN(price) AS minPrice FROM `".$config_databaseTablePrefix."products` GROUP BY `ean`";
mysqli_real_query($link,$sql);
$result = mysqli_use_result($link);
print "name,brand,price,imageLink,link\n";
$baseHREF = "http".(isset($_SERVER["HTTPS"])&&$_SERVER["HTTPS"]?"s":"")."://".$_SERVER["HTTP_HOST"];
while($row = mysql_fetch_array($result,MYSQL_ASSOC))
{
$imageLink = $baseHREF.$config_baseHREF."imageCache.php?src=".base64_encode($row["image_url"]);
$link = $baseHREF.tapestry_productHREF($row);
print $row["name"].",";
print $row["brand"].",";
print $row["minPrice"].",";
print $imageLink.",";
print $link."\n";
}
?>
Hope this helps!
Cheers,
David.
