| accessforbidden | ( | $message = '', | |
| $printheader = 1, | |||
| $printfooter = 1, | |||
| $showonlymessage = 0, | |||
| $params = null ) |
Show a message to say access is forbidden and stop program.
This includes HTTP and HTML header and footer (except if $printheader and $printfooter is 0, use this case inside an already started page). Calling this function terminate execution of PHP.
| string | $message | Force error message |
| int | $printheader | Show header before |
| int | $printfooter | Show footer after |
| int | $showonlymessage | Show only message parameter. Otherwise add more information. |
| array | null | $params | More parameters provided to hook |

Check that access by a given user to an object is ok.
This function is also called by restrictedArea() that check before if module is enabled and if permission of user for $action is ok.
| User | $user | User to check |
| array | $featuresarray | Features/modules to check. Example: ('user','service','member','project','task',...) |

| string | $tableandshare | 'TableName&SharedElement' with Tablename is table where object is stored. SharedElement is an optional key to define where to check entity for multicompany modume. Param not used if objectid is null (optional). |
| array | string | $feature2 | Feature to check, second level of permission (optional). Can be or check with 'level1|level2'. |
| string | $dbt_keyfield | Field name for socid foreign key if not fk_soc. Not used if objectid is null (optional). Can use '' if NA. |
| string | $dbt_select | Field name for select if not rowid. Not used if objectid is null (optional). |
| string | $parenttableforentity | Parent table for entity. Example 'fk_website@website' |

| dol_hash | ( | $chain, | |
| $type = '0', | |||
| $nosalt = 0 ) |
Returns a hash (non reversible encryption) of a string.
If constant MAIN_SECURITY_HASH_ALGO is defined, we use this function as hashing function (recommended value is 'password_hash') If constant MAIN_SECURITY_SALT is defined, we use it as a salt (used only if hashing algorithm is something else than 'password_hash').
| string | $chain | String to hash |
| string | $type | Type of hash ('0':auto will use MAIN_SECURITY_HASH_ALGO else md5, '1':sha1, '2':sha1+md5, '3':md5, '4': for OpenLdap, '5':sha256, '6':password_hash). Use 'md5' if hash is not needed for security purpose. For security need, prefer 'auto'. |
| int | $nosalt | Do not include any salt |
