here is simple script to remove extra white spaces from each field of database table and get log record of how many fields age getting affected ! !

<?php
mysql_connect("localhost","root","");
mysql_select_db("temp");
if(isset($_GET['table']))
{
define("TABLE_NAME",$_GET['table']);
$sql = "select * from ".TABLE_NAME." ";
$rs = mysql_query($sql);
while($row = mysql_fetch_array($rs))
{
$flag = 0;
$i = 0;
foreach($row as $key => $value) {
if($flag == 0) {
$flag = 1;
} else {
$flag = 0;
$trimed = trim($value);
$temp = "update ".TABLE_NAME." set ".$key." = '".$trimed."' where id = '".$row[0]."' ";
mysql_query($temp);
if(mysql_affected_rows() == "1")
{
$i++;
echo "field trimed at id = ".$row[0]." and field = ".$key."";
}
} } }
if($i == "0") {
echo "no rows affected";
}
echo "DATABASE table trimed successfully";
}
else {
echo "no table defined";
}
?>

Often when one installs the CMS Made Simple on an active server online; they face a problem with the Tiny MCE editor in the pages section and hence the content cannot be modified via the editor.

I have provided three known solutions to this problem:
1) Change the permission on the modules directory to 755 if it already isn’t.
2) Try uninstalling the Tiny MCE and reinstalling it.
3) Try uninstalling the Tiny MCE and replacing it with an older version.

To add the banners in the zencart just follow the three steps.

1. Open the zencart database and insert one record in the “Configurations” table.

1. Keep the configuration_id null(it will update automatically)
2. Write the title for e.g.’Banner Display Group All pages left‘ in configuration_title.Layout Settings on the Admin side.
3. In configuration_key write the tag ‘SHOW_BANNERS_GROUP_SET10‘

   Note: SET10 is the id of sets of banner. Upto SET9 all are the default banners of zencart.Update the SET no. everytime you want to add banners such as SHOW_BANNERS_GROUP_SET11,SHOW_BANNERS_GROUP_SET12 and so on….

4. In the configuration_value write any value such as’left_banner2‘

   Note : This value will be the group name of your banner and it will be added in the dropdown list of the banner groups when you will add the new banner from admin.

5. Add any description in “configuration_description” field.
6. Just write ‘19‘ in the “configuration_group_id” as 19 is the id for the banners.
7. Just give the unique id for the “sort_order field” for the group_id 19.Generally start after id 75.The value must increment every time you add the new banners.
8. Keep all other fields as it as and save the record.

2. On the admin side click on new banner button in the Banner Manager.

1. Give the title for the banner such as New Banner.
2. Give the url in url box if you want to add such as http://www.google.com
3. Now select the group from the dropdown box.Your newly created group will be added there. Select it.
4. Upload the image you want to display as banner and click on insert.

Your banner has been created now.

3. To display the banner in the site just copy the following code and paste it where you want to display the banner.

 <?php
  if (SHOW_BANNERS_GROUP_SET10 != '' && $banner = zen_banner_exists('dynamic', SHOW_BANNERS_GROUP_SET10)) {
if ($banner->RecordCount() > 0) {
echo zen_display_banner('static', $banner);
    }
  }
?>

That’s it.You can see the banner now. I hope it works.

If you ever feel the need to install a language pack in magento it can be done by selecting the key from the magento commerce site(extensions) for the respective language pack. However the Spanish language key given (magento-community/Locale_Mage_community_es_MX) may not work hence you can use an alternative mentioned below:
magento-community/Locale_Mage_community_es_MX-1.0.19870.4.5

If the above method of installing a language pack fails then browse to the site mentioned below and download the language pack:

http://www.magentocommerce.com/langs

You will need to install it manually however.

The language can be configured from the configuration menu in the admin by setting the locale.

Recently I have face strange issue on wordpress which is “public_html/wp-includes/pluggable.php on line 868 wordpress issue” error at the time of login on wordpress website.

Issue: public_html/wp-includes/pluggable.php on line 868

Solution: This kind of error is normal for wordpress. This can occur due to some spaces after ?> ( end of php code ) in your php code files. So, you need to check your last accessed files and removed spaces if there and try again accessing that page. Hope it helps for wordpress developers.

Now we will see one example how to combine pdf files

let us assume we have 1.pdf,2.pdf,3.pdf files and now we need to cobmine this files using the following command

gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=combinedpdf.pdf -dBATCH 1.pdf 2.pdf 3.pdf

the output file will be combinedpdf.pdf

Rename “1.pdf 2.pdf 3.pdf” to whatever your file names are (separate your file names with a space).

If you want to know more options available for gs command check main page
