Else in foreach looping - php

Question

What I want if the result is not found from the query select, I want to show else function like:
else {
$html .= 'You have not added stock at all';
}
Because in this case I used string of html, I don't know how to echo the else statement.
More or less my codes is looking like this right now (There are many parts I have removed since it's too long)
<?php
include("../actions/config.php");
$resultsClaim = $mysqli->query("SELECT");
$orders = array();
$html = '';
if ($resultsClaim) {
while($obj = $resultsClaim->fetch_object()) {
$orders[$obj->id_cart][$obj->items] = array('status' => $obj->status ...);
}
foreach ($orders AS $order_id => $order) {
$orderCount = count($order);
$html .= '<tbody><tr><td rowspan="' . count($order) . '">' . $order_id . '</td>';
$row = 1;
foreach ($order AS $item => $data) {
if ($row > 1) { $html .= '</tr><tr>'; }
$html .= '<td>' . $item . '</td>';
$row++;
}
$html .= '<div>
<div class="member-popUpeStock'.$data['id'].' member-PopUp">
<div class="member-PopUp-box">
X
<div class="tablePopUp">
<div class="table-row">
<div class="col">: '.$data['method'].' </div>';
///HERE WHERE I WANT TO DO THAT////
else {
echo 'Nothing';
}
echo $html;
?>
Can anyone help me, please! Thanks in Advance.

Answer 1

Since you are taking the no of orders into a variable, you can make use of that directly to see if the orders exists or not.
$orderCount = 0; //Define orderCount in the beginning.
//Rest of the code, till foreach
foreach(){
//Rest of the code here
}
if(intval($orderCount) <= 0) //Using intval, for the case the for loop is not executed at all
{
$html = "Nothing";
}
Here you dont need to concatenate it to $html since you are displaying the table content if order exists or else you displaying "Nothing".
So $html will either have the table content or else "Nothing".
Hope this helps.

Answer 2

First get count of $orders
if (! empty($orders)) {
foreach ($orders AS $order_id => $order) {
// YOUR CODE HERE
}
}
else {
$html .= 'Nothing'; // Append your `no records found` message to the `$html` variable:
}

Answer 3

foreach ($orders AS $order_id => $order) { } else {}
So "}" is missing for foreach loop. Hope it will work for you. Let me know if you need further help.

Answer 4

Give it a try
<?php
include("../actions/config.php");
$resultsClaim = $mysqli->query("SELECT");
$orders = array();
$html = '';
if (!empty($resultsClaim)) {
while ($obj = $resultsClaim->fetch_object()) {
$orders [$obj->id_cart][$obj->items] = array('status' => $obj->status);
}
foreach ($orders AS $order_id => $order) {
$orderCount = count($order);
$html .= '<tbody><tr><td rowspan="' . count($order) . '">' . $order_id . '</td>';
$row = 1;
foreach ($order AS $item => $data) {
if ($row > 1) {
$html .= '</tr><tr>';
}
$html .= '<td>' . $item . '</td>';
$row++;
}
$html .= '<div>
<div class="member-popUpeStock' . $data['id'] . ' member-PopUp">
<div class="member-PopUp-box">
X
<div class="tablePopUp">
<div class="table-row">
<div class="col">: ' . $data['method'] . ' </div>';
}
}
///HERE WHERE I WANT TO DO THAT////
else {
echo 'Nothing';
}
echo $html;
?>
