Osclass Tips and Tricks:

In the following I will show you some of the best tips and tricks you can do with Osclass.

Errors

Check your errors using Osclass Debug Read, a plugin created for simple users because you do not need FTP access or cPanel access and you just need to activate the PHP debug.

Helper’s functions

You can always use the helpers’ functions which are also used by themes, scripts and Osclass plugins. These contain vital information for your Osclass.

Price format

You can always change the price format by changing the language in the administration panel. Here you can add or remove a format as you wish.

Terms plugin

Using the Terms plugin you can easily display a checkbox with terms and condition of your website on the publication page of an ad. If the user does not check the box, he will not be able to finish the publication of the ad he wrote. You do not need to modify the theme you use. However if you want to change the position of the checkbox you should also modify the theme.

Simple Message

Most of the simple classifieds ads are not having a message system between the seller and the possible client. S Message or also named Simple Message is used to communicate with your seller or with your client on an Osclass website. You can even block users and you can also see a history of your sent message in your administration panel.

Javascript errors

You can always find Javascript errors if you use your browsers inspect element tool. Nowadays all modern browser are coming with an included tool regarding the inspection of a website’s source code. Both Chrome and Firefox have this kind of tool where you can see the HTML, CSS, and Javascript tools and you can even modify them to see how an element looks with your modification.

Auto Delete Users

You can easily delete old users which are no longer active on your Osclass by using the Auto Delete Users. This plugin also deletes users which did not confirm their account and you can schedule an automatic check of users. Auto Delete Users uses cron and you need to activate cron in the general Osclass settings.

Translating custom fields

To translate custom fields in Osclass you need to modify the Osclass core. Most of the modifications are made in the field.form.class.php file from the oc-content/Osclass/frm folder. Here you need to find the static public function meta using CTRL+F function of your editor. Now you should replace for each custom field the following code $field[‘s_name’] with __($field[“s_name”]). Next, you just need to translate the core.po file from the language folder using any type of text editor. However, I recommend you to use Poedit in order to save change in the core.mo file when you are saving the core.po file.

Osclass Cron

You can run multiple commands and scripts at scheduled period of times using the Osclass Cron. This offers you the possibility to use commands at every hour, day or week. You also need to enable this function from the administrator panel of Osclass. To run a cron script you need to use the following code:

function my_cron_job(){}
osc_add_hook('cron_hourly', 'my_cron_job');

where cron_hourly is for each hour and cron_daily for each day while cron_weekely for each week.

To see which PHP files your Osclass theme is using you need to write down at the end of functions.php from your theme the following code:

function which_file() {
$theme_name = osc_theme();
$included_files = get_included_files();
$matches = array();
foreach ($included_files as $k => $v) {
if (preg_match("/\b$theme_name\b/i", $v)) {
echo $matches[$k] = $v;
}}}
osc_add_hook('footer', 'which_file')

PayGol

Using the PayGol plugin you can enable PayGol payment for your Osclass. PayGol offers the possibility to make payment from short text messages, card, phone call or wire transfer.

Maintenance page

You can always change the maintenance page by creating a maintenance.php file in your theme’s folder. Next you need to add a code which tells your users that the web site is in maintenance. To use your theme’s styling you just need to enter the following code:

<link href="<?php echo osc_current_web_theme_url('css/main.css') ; ?>" rel="stylesheet" type="text/css" />

Placeholder

If in an ad there is not available an image, then usually the Osclass themes have a placeholder. You can display images from the same category product instead of the placeholder. To do this, you need to modify multiple files from your theme.

For example, for Bender theme, you need to modify loop-single.php and loop-single-premium. In these two files you need to replace the following code:

<img src="<?php echo osc_resource_thumbnail_url(); ?>" title="" alt="<?php echo osc_esc_html(osc_premium_title()) ; ?>" width="<?php echo $size[0]; ?>" height="<?php echo $size[1]; ?>">

with this one:

<img src="<?php if(file_exists(osc_themes_path() . 'bender/images/category/' . osc_item_category_id() . '.png')) { echo osc_base_url() . 'oc-content/themes/bender/images/category/' . osc_item_category_id() . '.png'; } else { echo osc_base_url() . 'oc-content/themes/bender/images/no_photo.gif'; } ?>" alt="<?php echo osc_esc_html(osc_premium_title()) ; ?>" width="<?php echo $size[0]; ?>" height="<?php echo $size[1]; ?>" >

In the end you also need to create another category folder in your images folder of your theme where you put all the images you want to use for each category.  Each image will be renamed after the category id and will have a name like: example 1.png.

How to add a Facebook share button

If you want your users to be able to share the content of your websites such as an ad or a page on Facebook, you should definitely use a Facebook share button. Not only that using this button your users can share content from your website, but also you get more users. In order to create a Facebook share button, you first need to go at Facebook Developers where you should activate your developer account. Next, you should copy the share button script and put it in the item.php file where you want to appear. The widget’s code is:

<a name="fb_share" type="button_count" href="http://www.facebook.com/sharer.php">Share</a><script type="text/javascript" src="https://static.ak.fbcdn.net/connect.php/js/FB.Share" ></script>

Referral plugin

There is a referral plugin available on the Osclass market. You should download it because it is free. You can use it for yourself or your users offering them the possibility to have featured ads with the credit obtained from referrals.

How to add PHP code

Some of Osclass pages cannot be customized as you wish. Those pages are usually created in the administration dashboard and usually, their content is stored in the database and not as a PHP file in FTP.

If you want to add PHP code to this kind of pages, you should make a quick test to a new one by creating a page without description. Next, you should create a new page in FTP named page-example.PHP, where the example is replaced with the name of the page you just created in the administration dashboard. If you do not follow this rule, you cannot add PHP code to a web page created in the Osclass administration dashboard. Now if you save and upload the file to your themes folder you can see that everything written there automatically appear in the dashboard also. Now you can even add PHP code if you want not just videos, images, and HTML code from the Osclass dashboard editor.

How to change the administrator password in PHPmyAdmin

First, you need to log into your cPanel and go to PHPmyAdmin. Here you should choose to appear all Osclass tables. Now select the only oc_t_admin table and then press the edit link. You can see that the field s_password is the one which stores the administrator password. You only need to delete everything from this field and then you just need to write your own new password. After that, you should choose the security option for scripting as SHA1. Now press the Go button and all the changes are saved and you can also use the new password.

How to upload themes and plugins

If you are a developer, you can make themes and plugins for Osclass and you can also upload them in the Osclass Market by login into the Market and at My products section you can add new item by filling in the information description, title, category, price if it is the case and other important information. Next, click Submit and then simply upload your file. Do not forget to write the Osclass versions which are compatible with it and also the upload process can be a little longer than expected due the large file you are uploading or due the internet connection.

Search engine optimization tips and tricks

Once you made your website fully functional and with the proper design you just need to follow a couple of advice regarding SEO in order for Google and other search engine send their bots: Google Bot, MSN Bot, Ask.com Bot to index faster your website. These devices are the following ones:

You also need to rename the en_US folder in the languages folder of every plugin by giving the proper ISO name of the language you want such as de_DE for Germany, en_UK for British English and so on. Next, you need to open the messages.po file with Poedit and translate editing like in the following example:

msgid “The English version”
msgstr “Your translation”

For plugin where the languages folder does not exist, you need to create the folder and to copy from another plugin the messages.pro, deleting everything from it excepting the first line. Next, you need to write for each message two lines like the above ones.
