installation

1- composer require mahmoud-abdelfadeil/validator-filter-php

ConfigeFile

create config file Through the following command :
php vendor/mahmoud-abdelfadeil/validator-filter-php/src/Validator/create-file-config.php

Or create a config file by writing these lines into the composer.json file , Then command composer dump-autoload

{
    
    "scripts": {
        "post-autoload-dump": [
           "php  vendor/mahmoud-abdelfadeil/validator-filter-php/src/Validator/create-file-config.php"
        ]
    }
}

Then the file is created config/validator-filter-config.php

return [
    // config database
    "db_host"=>"localhost",
    "db_connection"=>"mysql",
    "db_name"=>"filter-validate-php",
    "db_user"=>"root",
    "db_password"=>"",



    // config langauge [ar - en]
    "lang"=>'en'
];

It is a settings file that makes settings for Database and language settings

Validate

It is intended to verify the value

There are several functions of them

Syntax

/*
$arr=[
    request name = > rules
]
*/
// example
include 'vendor/autoload.php';
$validate=new ValidatorFilterPHP\ValidatorPHP();
$rules=[
    'name'=>'required|string|max_length:100|min_length:5',
    'age'=>'required|number|max_val:60|min_val:10',
    'email'=>'required|unique:users,email'
];

if(isset($_POST['submit'])){
    $validate->Validator($rules);
    if($validate->has_error_validate()){
        echo "<pre>";
        print_r( $validate->has_error_validate());
    }else{
        // next request
    }
}

NotesSyntax

As we noticed in the previous example, we write the name of the request, then the rules to be verified, and each rule is separated by using the ' | '

There are many rules that we need to write a value, for example the max_length, which means the minimum number of characters, and the rule and value are separated using the ' : '

Rules

string

Check the value if it is textual or not

number

Check if the value is a number or not

url

Check if the value is a url or not

required

Check if the value is empty or not

options

It forces the user to enter the specified values ​​into the options
From a rule that takes specified values ​​but is written this way :

options:[option 1 , option 2 , .......]

// example 
'category'=>'required|options:[car,laptop,mobile]'

ip

Check if the value is a ip or not

email

Check if the value is a email or not

max_length

Checks the maximum amount of characters allowed

min_length

Check the minimum number of characters allowed

example

// maximum length  100  characters
// minimum length  5    characters

'name'=>'required|max_length:100|min_length:5'

max_val

Check the maximum allowed value

min_val

Check the minimum allowed value

// maximum value  60
// minimum value  20    

'age'=>'required|max_val:60|min_val:20'

**Note:The max_length or min_length is used with the string. The max_val and min_val are used with numbers . In addition, they check if it is a number or not**

uniqueAndExists

Before dealing with either of them, make the database settings from the config/validator-filter-config.php

return [
    // config database
    "db_host"=>"localhost",
    "db_connection"=>"mysql",
    "db_name"=>"filter-validate-php",
    "db_user"=>"root",
    "db_password"=>"",



    // config langauge
    "lang"=>'en'
];

unique

Verify that the value is not present in the data base
Synax :
unique:table,column

// example  

'email'=>'required|unique:users,email'

Here, verify that email does not already exist in Databases
**If modified, the identifier is sent with the unique identifier to check all rows except for the sender and write in this way The id field name for example tbl_id and then the value that way tbl_id = 5**

// example  if update data

'email'=>'required|unique:users,email,tbl_id=5'

If the field is named id, you only need to enter the value

'email'=>'required|unique:users,email,5'

exists

Synax :
exists:table,column
Verify that the value is present in the data base

// example  

'email'=>'required|unique:users,email'

Filters

a data filter
Syntax :
$obj->functionName($data)

// example
$filter=new ValidatorFilterPHP\FilterPHP();
$str="<script>mahmoud abdelfadeil</script>";
$str_filter =  $filter->string($str);

echo $str_filter ;

// output  = mahmoud abdelfadeil

functions

string

$str="<script>mahmoud abdelfadeil</script>";

$str_filter =  $filter->string($str);

echo $str_filter ;

// output  = mahmoud abdelfadeil

num_int

number integer

$data="<script>mahmoud 1299 abdelfadeil</script>";

$data_filter =  $filter->num_int($data);

echo $data_filter ;

// output  = 1299

num_float

number float

$data="12.99";

$data_filter =  $filter->num_float($data);

echo $data_filter ;

// output  = 1299

However, this function takes a second argument, which is the flag
Flags = e or E or , or .

$data="12.99";

$data_filter =  $filter->num_float($data,'.');

echo $data_filter ;

// output  = 12.99

$data="12,99";

$data_filter =  $filter->num_float($data,',');

echo $data_filter ;

// output  = 12,99

$data_1="12ee9e9";

$data_1_filter =  $filter->num_float($data_1);

echo $data_1_filter ;

// output data 1   = 1299

$data_2="12ee9e9E";

$data_2_filter =  $filter->num_float($data_2,'e');

echo $data_2_filter ;

// output data 2   =  12ee9e9E


$data_3="12ee9e9E";

$data_3_filter =  $filter->num_float($data_3,'E');

echo $data_3_filter ;

// output data 3   =  12ee9e9E

email

$data="mahmoud .  €¶€€¶€€¶€  [e-mail]";

$data_filter =  $filter->email($data);

echo $data_filter ;

// output data    =  [e-mail]
 

url

$data="mahmoud-abdelfadeil.€¶€¶€me";

$data_filter =  $filter->url($data);

echo $data_filter ;

// output data    =  mahmoud-abdelfadeil.me
 

encoded

$data="mahmoud-abdelfadeil.€¶€¶€me";

$data_filter =  $filter->encoded($data);

echo $data_filter ;

// output data   =   mahmoud-abdelfadeil.%E2%82%AC%C2%B6%E2%82%AC%C2%B6%E2%82%ACme
 

magic_quotes

$data="mahmoud's here";

$data_filter =  $filter->magic_quotes($data);

echo $data_filter ;


// output data =  mahmoud\'s here
 

special_char

$data="<b>mahmoud abdelfadeil</b>";

$data_filter =  $filter->special_char($data);

echo $data_filter ;

// output data = &#60;b&#62;mahmoud abdelfadeil&#60;/b&#62;
