class="materialize-input">
<input id="email" name="email" maxlength="40" type="email"
class="materialize-input">
<input id="phone" name="phone" maxlength="40" type="text" maxlength="40"
class="materialize-input">
<select multiple id="00N7F000001F2kO" name="style" multiple="multiple" >
<option name="consulting" name="styling" value=""selected disabled>image
consulting</option>
<option value="1">styling</option>
<option value="2">hair & make-up</option>
<option value="3">designing clothes</option>
<option value="4">wedding makeover</option>
<option value="5">personal shopper</option>
<option value="6">corporate services</option>
</select>
</form>

Answer 1

you have to specify in the name of the select that it will be an array like :
<select multiple id="00N7F000001F2kO" name="style[]" multiple="multiple" >
<option value=""selected disabled>image consulting</option>
<option value="1">styling</option>
<option value="2">hair & make-up</option>
<option value="3">designing clothes</option>
<option value="4">wedding makeover</option>
<option value="5">personal shopper</option>
<option value="6">corporate services</option>
</select>
and then you can implode it if you want a string like this
implode(',',$_POST['style']);
EDIT :
change this
$style = $crud->escape_string($_POST['style']);
to
$style = $crud->escape_string(implode(',',$_POST['style']));

Answer 2

you need to use an array for multiple select options :
<select multiple id="00N7F000001F2kO" name="style[]" multiple="multiple" >
<option name="consulting" name="styling" value=""selected disabled>image
consulting</option>
<option value="1">styling</option>
<option value="2">hair & make-up</option>
<option value="3">designing clothes</option>
<option value="4">wedding makeover</option>
<option value="5">personal shopper</option>
<option value="6">corporate services</option>
</select>
this is how tou get the data into your database :
.php
if(isset($_POST['styling']) && !empty($_POST['styling'])){
$Col1_Array = $_POST['styling'];
print_r($Col1_Array);
foreach($Col1_Array as $selectValue){
//show selected
echo $selectValue."<br>";
}
}
