# Backend customizing (V. 4.8.x)

## Introduction

Backend customizing is a mechanism to customize various parameters of the backend. There are not many settings you can do, as this mechanism is relatively new. However, this mechanism will be used more and more in the future.

## How it works

Customizing Contenido settings is very easy and can be done via the group or user customizing settings. Here's an example for the user customizing:
Important: User settings have precendence before group settings. User settings always override group settings. If the user is added to more than one group, the result is undefined. Make sure that your groups don't override each other.

## Common parameters

Area/Type | Property | Value (Description) | Applies to
backend | currentlogintime | Date and Time when this session has been started (automatically set by the backend) | Users
backend | lastlogintime | Date and Time when the last session was started (automatically set by the backend) | Users
backend | preferred_idclient | ID of the client which should be selected after backend login | System, Clients, Groups, Users
backend | leftframewidth | Defines the width of the left frame. Standard value is 250. | System, Clients, Group, Users
backend | small-navigation | (true, false): If true, a small navigation is shown. Default: false | System, Clients, Groups, Users
articles | show-new-window-checkbox | (true, false): If true, show "new window" checkbox for redirects in article properties. Note: If a redirect has been specified, the page is redirected to the new URL using an html page header. As header redirects can't open new windows, this setting is only useful, if a navigation module is used, which mentions the "open in new window" setting and adds a ′target="_blank"′ to the link, if necessary. Default: false | System, Clients, Groups, Users
cms_img | directory-height | Height of the directory lister in rows, default 5 | System, Groups, Users
cms_img | directory-width | Width of the directory lister in pixels, default 300 | System, Groups, Users
cms_img | file-height | Height of the file lister in rows, default 5 | System, Groups, Users
cms_img | file-width | Width of the file lister in pixels, default 300 | System, Groups, Users
cms_img | description-height | Height of the description box in rows, default 5 | System, Groups, Users
cms_img | description-width | Width of the description box in characters, default 70 | System, Groups, Users
cms_img | preview-height | Height of the preview area in pixels, default 400 | System, Groups, Users
cms_img | preview-width | Width of the preview window in pixels, default 600 | System, Groups, Users
imagemagick | available | Set "1" if ImageMagick is available on your server to receive best results when resizing images | System, Groups, Users
modules | java-edit | Enable the java module editor | System, Groups, Users
modules | edit-with-tabs | (true, false) If set to "true" you can use the <tab> key to insert tabs in the input and output code areas (IE 6/7, FF 1.5/2). Default: false | System, Clients, Groups, Users
modules | disable-history | (true, false) If true, don't use the module history. Default: false | System, Clients, Groups, Users
modules | storeasfiles | Defines if Contenido should store modules as text files. THIS IS HIGHLY EXPERIMENTAL, ONLY USE IF YOU KNOW WHAT YOU ARE DOING! Default off. | System
modules | loadfromfiles | Defines if Contenido should load modules as text files. THIS IS HIGHLY EXPERIMENTAL, ONLY USE IF YOU KNOW WHAT YOU ARE DOING! Default off. | System
modules | force-menu-check | If system/modulecheck is enabled, force module check while module list will be generated (instead of using database information). Default $quot;false$quot;. | System, Clients, Groups, Users
system | modulecheck | if set to "false" (as string), modules aren't tested for syntax errors (needed for older PHP versions) | System
system | languageorder | If set to "name", languages in the drop-down (top right) will be shown ordered by name, if not specified or set to something else, languages will be ordered by language id (default) | System, Clients, Groups, Users
system | multiassign | If false, don't allow multi assignments for articles. | System, Clients
layout | htmlvalidator | (true, false): If true, use the HTML validator. Default: true | System, Groups, Users
newsletter | option-cronjob-available | (true, false): If true, then a newsletter option can be activated to send the newsletter using cron jobs. Note, that this option should only be used, if a real cron service is available (do not use the Contenido built-in pseudo cron service). Additionally, note, that there is a send job file available in the contenido/cronjobs folder, but it hasn't been added to the cron job list - just generate a real cron job on your server running this file. Default: false | System, Clients, Users
newsletter | disable-rn-replacement | (true, false): If true, "\r\n" will not be replaced by just "\n" to prevent double lines in mails. This may be a good idea on Windows-Servers. Usually, use the default setting. Default: false | System
newsletter | remove_base_tag | (true, false): Usually every article contains a "e;base href"e; tag. This is nice, as all links, URLs and sources can be relative and we can move the client around, as we like. But there is a problem with anchors: They only work, if the link to the anchor (on the same page) contains the URL of the current article (e.g. "front_content.php?idart=77#MyAnchor"). This works fine, if you are on the website, but not, if you use anchors in html newsletter articles (as the mail doesn't has this URL). If you like to use anchors in html newsletters, set this setting to "true" and check everything twice, as also all URLs and source path will be changed by Contenido code. Default: false | Client
newsletter | html_username html_password | If the frontend (the website) is proteced using .htaccess (username/password), you have to specify html_username and html_password to be able to send html newsletters (as html newsletters are just usual articles). Default: empty or not specified | Client
frontendusers | pluginsearch | (true, false): If true, the frontend users menu also searches trough plugins. However, searching trough plugins have a huge performance inpact on the list. If you have alot of frontend users, set this to false to disable this function. Default: true | System, Clients, Users
frontendusers | pluginsearch_valid_plugins | If pluginsearch is set to true, you can hereby limit the plugins to search over. This property must be a comma-separated list (no whitespaces) of all plugins that should be used for pluginsearch. All other plugins will be skipped to improve performance. | System, Clients, Users
generator | xhtml | (true, false): Defines if the tags generated by Contenido should be XHTML compliant. WARNING: This does not alter the HTML code in your layouts and modules! You have to revise your modules and layouts to be XHTML compliant. Default: false. | System, Clients
generator | basehref | (true, false): Defines if Contenido should automatically insert a base href tag. Default: true. | System, Clients
edit_area | activated | (true, false): Defines if syntax highlighting editor is used in backend for modul, js, css and html code Default: true. | System, Clients, Groups, Users
maintenance | mode | (disabled, enabled): In maintenance mode, only sysadmins are allowed to login into contenido backend. Default: disabled | System
pw_request | enable | (true, false): Property definies if contanido is allowed to generate new passwords for backenduser and submits them via mail. Default: true | System
system | mail_host | Host which is used for sending system mails (PW-Request). Default: localhost | System
system | mail_sender | Sender mail-adress of Contenido Systemmails. (PW-Request). Default: info@contenido.org | System
