This section describes how to perform category import to osCommerce from .csv file - bulk update categories.
Pay attention to each step while importing categories. Import is a rather complicated procedure and it may be destructive if performed incorrectly. It is strongly recommended to make database backup before importing categories, especially if you do it for the first time.
To import categories to osCommerce follow a few steps listed below:
1. First of all prepare a .csv file for further Import. Make sure it contains all the necessary fields and data you are going to import listed in the table.
If your vendor provides you product list in Excel, you can convert your Excel files to the CSV format within the Microsoft Excel or OpenOffice application by using the Save As option. You can then access the Save As dialogue box which contains a list of alternative file formats. Among the file extensions offered, you can find Text CSV file format. By saving your file into CSV format, Microsoft Excel or OpenOffice will export the first active worksheet with the correct delimiters.
2. Select "Import" and click "Next >" to proceed.
3. Specify the .csv file path and name or use browse button to select one.
4. Source file preview shows a part of .csv file
selected to import. There are no options to set anything, but you should pay attention to this page.
If you carefully check the very first line of the example, you'll notice that some words enclosed in quotes (") and are separated by semicolon (;) symbol. There are two important options you have to pay attention to: Select fields delimiter and quote character (if any are used). The next step describes how to setup these options. Usually it is enough to see first line, no need to investigate the entire file.
5. Select fields delimiter and quote character. If you specify wrong values, import may not work.
6. The next page allows you to Link columns from .csv file to appropriate database fields.
Specify the following options:
Note: It is recommended to use Category Name + Category Path to identify your categories. As new category IDs are generated automatically when you Import categories to osCommerce for the first time (import ignores your Category IDs). If you used to Export data to .csv file for further import, you may use Category ID identification method, otherwise use Category Name + Category Path.
Link columns from .csv file to appropriate database fields. The left pane "Database Fields" shows the list of fields in your database that can receive import data. So, to assign .csv column to database field you should select a field at the left pane and then click a column at the right pane.
Source .csv file can contain multiple records with identical Name values. All these categories will be considered as one - currently imported categories will overwrite previously imported with the same key field values. Note that sometimes one of key fields may be blank. Obviously blank fields contain the same value for all records. It is required to assign .csv columns to key fields.
Database Fields contain the following columns:
[Auto Fill...] button - try to set correspondence automatically for
all fields. Auto fill option will work only if .csv column name is the
same as database field name ("translated").
7. Base Formats and Separators are used to convert text values from .csv file to numerical and date values. You can just set default values using an appropriate button.
8. Categories were not imported to your database yet. On Preview Import page you can see how your .csv file processed using all import settings. Check whether all columns that you want to be imported contain data. Some of them may be blank. It means that you haven't assigned them or they are empty in source (.csv) file. Unassigned columns will not be imported, whereas empty values will overwrite existing.
If red blinking arrow appears, it means that some errors occurred and have to fix them. Attention! Import process will start, when you press "Import" Button! Proceed only if all settings are made, otherwise press "Back" Button and check the settings once more!
9. In the last window of osCommerce Import Categories Wizard you can see if any errors occurred during import.
Most frequent import errors are date, time and number conversion issues, caused by improper format settings (specified at previous page) or improperly assigned column (i.e. if you assigned column containing category ID to parent_category database field).
Date/time conversion errors might be ignored, whereas other errors like this one (Could not find image: image_name.gif) need to be fixed.
Now the import of categories to osCommerce is completed.
