The 'Get Many Where' Method

The 'Get Many Where' method is for fetching rows of data from a database table. It accepts the following parameters:

Use PHP's inbuilt var_dump() method whenever you need to clarify the variable types from a given results set.

What Gets Returned?


If matching records are found then a PHP array will be returned where each item on the array represents a row from a database table. Each row, within the array, will be a PHP object.


If the query fails to find any matching records then an empty array will be returned.

Example 1

The syntax below shows the simplest Get Many Where example possible. In this example, we are passing in a column name of 'first_name' and a value of 'Bruce'.

$rows = $this->model->get_many_where("first_name", "Bruce");

The code above will produce the following SQL query:

SELECT * from tablename WHERE first_name = 'Bruce'

In a working example, 'tablename' would be replaced with the first segment from the URL.

Below is an example of a Members.php controller file that contains a test() method. Here we're invoking a basic 'Get Many Where' command and then immediately displaying the results using Trongate's json() method:

<?php<br /> class Members extends Trongate {<br /> <br />     function test() {<br />         $rows = $this->model->get_many_where("first_name", "Bruce");<br />         json($rows);<br />     }<br /> <br /><br />

Below shows an example of the kind of output that we can expect to see from the above method, when Debug Mode is switched on:


Example 2

Below is a more advanced example:

$rows = $this->model->get_many_where("type", "Trout", "fish");

The code above would produce the following SQL query:

SELECT * FROM fish WHERE type = 'Trout'
