I want to be able to add an if statement in this result_2 string.
This is for displaying a product, and i would like to display price depending on users session value?
eg.
if ($_SESSION['customer_x'] == a) {
display price a
}
else if ($_SESSION['customer_x'] == b) {
display price b
}
Is this the correct method to be able to add an if statement to a JSON query?

Answer 1

After Starting your while loop, put a if else there,
$price ="";
if ($__SESSION['customer_x'] == a) {
$price='display price a';
}
else if ($_SESSION['customer_x'] == b) {
$price='display price b';
}
and now echo this price where ever you want to in your html
this is more neet and less messy way

Answer 2

You can use a ternary if operator to have conditional statements inside strings, example
$bool = false;
echo "The value of \$bool is " . ($bool == true ? "TRUE" : "FALSE");
Example in use

Answer 3

To add that you can keep doing the same but:
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){ // the next of the content
$priceOfSession = ($__SESSION['customer_x'] == a) ? 'pricea' : 'priceb';
$data['result_2'] .= '
<div class="col-sm-4 col-md-4">
'.$priceOfSession.'
</div>
</div>
<button type="submit" class="btn btn-primary">Add</button>
</form>
</div>
<!-- //.content-boxes-text -->
</div>
</div>
';
}
So if you want to evaluate only two conditions if otherwise the if you want, simply add it there. Do as you add the $ row but before defining value.
