I have a problem with this code, what happens is that I want to create a swap button to change two selectbox of place, such as the google currency converter and those of the internet, I would greatly appreciate your help if you taught me how to do it, the code I did with php. And an apology if I said something wrong I am a beginner in this world
// Output text
$out = $ans = $txtAmount =
// txtSelectBox1 selection
$selA0 = $selA1 = $selA2 = $selA3 =
// txtSelectBox2 selection
$selB0 = $selB1 = $selB2 = $selB3 = "";
// Check if form was submitted
if(isset($_POST['txtSelectBox1'])) {
// Get post values
$txtSel1 = $_POST['txtSelectBox1'];
$txtSel2 = $_POST['txtSelectBox2'];
$txtAmount = $_POST['txtAmount'];
// Exchange rates
$cur = array("MXN", "USD", "EUR", "JPY");
$php = array("1", "0.050", "0.048", "6.78");
$cad = array("20.12", "1", "0.96", "136.50");
$hkd = array("20.99", "1.04", "1", "142.51");
$jpy = array("0.15", "0.0073", "0.0070", "1");
// Switch statement for conversion
switch ($txtSel1) {
case "php":
$selA0 = ${"selB".$txtSel2} = "selected";
$ans = $txtAmount * floatval($php[$txtSel2]);
$case = 0;
break;
case "cad":
$selA1 = ${"selB".$txtSel2} = "selected";
$ans = $txtAmount * floatval($cad[$txtSel2]);
$case = 1;
break;
case "hkd":
$selA2 = ${"selB".$txtSel2} = "selected";
$ans = $txtAmount * floatval($hkd[$txtSel2]);
$case = 2;
break;
case "jpy":
$selA3 = ${"selB".$txtSel2} = "selected";
$ans = $txtAmount * floatval($jpy[$txtSel2]);
$case = 3;
break;
}
// Display output
$out = '<div class="answer">'.$txtAmount.' '.$cur[$case].' = '.$ans.' '.$cur[$txtSel2].'</div>';

my problem is that i have a page where you can add rows to a table and in the table is a drop down.
For the dropdown it should automatically keep the selected index and the next added row should be the same option selected as the row above.
That works however the row above does not keep the selected option and resets to the first option.
<?php
session_start();
require_once '../../connect/db.php';
include '../../functions/function.php';
if(!isset($_SESSION['row'])){
$_SESSION['row'] = 1;
}
$def = 4;
$pass = 5;
$run = 3;
if(isset($_POST['add'])){
$_SESSION['row']++;
}
if(isset($_POST['reset'])){
$_SESSION['row']=1;
}
?>

I have been working on a form that allows entering a menu item for a cafe establishment, alongside its ingredients (arrays of data). Unfortunately, a problem came up as it only executes 1 query even though 2 or more ingredients were entered in the form (dynamic, jQuery).
Here is the PHP code:
<?php
include("session.php");
if (isset($_POST['submit'])) {
$productname = $_POST['product_name'];
$categoryID = $_POST['categoryID'];
$price = $_POST['srp'];
// ingredients
$ingredients = $_POST['ingredients'];
$qty = $_POST['qty'];
$measure = $_POST['measure'];
if (!empty($productname) && !empty($categoryID) && !empty($price) && !empty($ingredients) && !empty($qty) && !empty($measure)) {
for ($i=0; $i < count($ingredients); $i++) {
if ($ingredients[$i] != "" && $qty[$i] != "" && $measure[$i] != "") {
mysqli_query($db, "insert into individual_ingredients values ('', '$productname', '{$ingredients[$i]}', '{$qty[$i]}', '{$measure[$i]}')");
}
}
mysqli_query($db, "insert into end_products values ('', '$productname', '$price', '', '$categoryID')");
mysqli_query($db, "insert into audit_trail values ('', now(), '{$_SESSION['login_user']}', 'New end product added')");
header("location: end_products.php");
} else {
echo '<font color="red">'."Incomplete data entered".'</font>';
}
}
?>
And here is the HTML form and JQuery:

It'd be great if someone could show me where I'm going wrong and help me get it going. :)

If you want to make a converter, all you need is one input - and a dropdown between what you wish to convert to. Then use a switch in PHP when the form was submitted to check what function you wish to use.
Your current issue is that you overwrite a lot of values, and that you don't check for the right buttons. This is also over-complicating it.
You can further develop this converter by making sure that the input is an actual number - by using filter_var() with a flag that's suitable for your need. You can either validate it or sanitize it, see FILTER_SANITIZE vs FILTER VALIDATE, whats the difference - and which to use?.
<?php
if (isset($_POST['submit'])) {
switch ($_POST['convert']) {
case "cm-in":
$result = centimeter_to_inches($_POST['value']);
$old_unit = 'cm';
$new_unit = ' inches';
break;
case "in-cm":
$result = inches_to_centimeter($_POST['value']);
$old_unit = ' inches';
$new_unit = 'cm';
break;
case "f-c":
$result = fahrenheit_to_celsius($_POST['value']);
$old_unit = ' Farenheit';
$new_unit = ' Celcius';
break;
case "c-f":
$result = celsius_to_fahrenheit($_POST['value']);
$old_unit = ' Celcius';
$new_unit = ' Farenheit';
break;
}
}
function fahrenheit_to_celsius($given_value) {
return 5/9*($given_value-32);
}
function celsius_to_fahrenheit($given_value) {
return $given_value*9/5+32;
}
function inches_to_centimeter($given_value) {
return $given_value/2.54;

I have a multiple select on my code, what I need to do is to have a validation when the user click the submit button without selecting any of the given list.
Here's the sample code:
index.php
<?php
IF(isset($_POST['Rtype'])){
$RetrieveType = $_POST['Rtype'];
IF($RetrieveType == 'date_range'){
$start_date = new DateTime($_POST['start_date']);
$sd = date_format($start_date,'Y-m-d');
$p_week=array();
$m_month=01;
$end_date = new DateTime($_POST['end_date']);
$end_date-> add(new DateInterval('P1D'));
$ed =date_format($end_date,'Y-m-d');
}
ELSEIF($RetrieveType == 'weekly'){
$p_week = $_POST['week'];
$m_week = implode(',',$p_week);
$m_month =$_POST['month_m'];
$m_year =$_POST['year_m'];
$p_lob = $_POST['lob'];
$sc_lob=implode(',',$p_lob);
} ELSE
{
$RetrieveType = 'date_range';
$sd = date('Y-m-01');
$start_date = date('Y-m-01');
$ed = date('Y-m-d');
$end_date = date('Y-m-d');
$m_month=date ('m');
$p_week=array();
$m_year= date ('Y');
$sc_lob='';
}
?>
<html>
<head>
<head>
<body>
<form action="index.php" method="POST" class="form-inline">
<label for="sel1">Week:</label>
<select data-placeholder="<?php echo (isset($_POST['week']) ? "Week/s Currently Selected: ".implode(",",$_POST['week']) : "Select Week"); ?>"
class="chosen-select" multiple tabindex="4" style="width:350px;" name= "week[]">
<option value="1" id="empty">Week 1</option>
<option value="2" id="empty">Week 2</option>
<option value="3" id="empty">Week 3</option>
<option value="4" id="empty">Week 4</option>
<option value="5" id="empty">Week 5</option>
</select>
<label for="sel1">LOB:</label>
<select data-placeholder="<?php echo (isset($_POST['lob']) ? "LOB/s Currently Selected: ".implode(",",$_POST['lob']) : "Select LOB"); ?>"
class="chosen-select" multiple tabindex="4" style="width:350px;" name= "lob[]">
<?php
$lob = array();
$q = "SELECT distinct LOB from roster where EmployStatus='active' and SDLead <> '' group by LOB";
$params = array();
$query = sqlsrv_query($conn, $q);
while($rowsss= sqlsrv_fetch_array($query)) {
$lob = $rowsss['LOB'];
echo "<option value='".$lob."'>".$lob."</option>";
}
for ($i = 0; $i <= count($lob) - 1; $i++) {
IF($sc_lob == $lob[$i])
{$isSelected = 'selected';}
elseif(1==1)
{$isSelected='';}
echo "<option ".$isSelected." value='".$lob[$i]."'>".$lob[$i]."</option>"; }
?>
<input type="hidden" name="Rtype" value="weekly">
<input class="btn btn-primary" type="submit" />
</form>
What I wanted to achieve is when the user clicked the submit button without selecting any on the "Week" list or "LOB" list, there would be an error message that says "This field is required, select at least one.". Actually I already did this before, when I'm just using a checkbox. I placed the code below after the label tag:
sample code:
<?php
if(isset($_GET['err']))
{
$err = $_GET['err'];
if($err == 1)
{
echo "<span class='text-danger'>* This field is required, select at least one.</span>";
}
else
{
echo "";
}
}
else
{
echo "";
}
?>
Try this
if(isset($_POST['submit']){
errors = 0;
if($_POST['nameOfSelect'] == ""){
errors++;
}
if(errors == 0){
return true;
}else{
return false;
}
I got this code but it is not inserting the content of the option (textarea) into the database.
connection.php
<?php
$dbhost = "localhost";
$dbuser = "root";
$dbpass = "";
$db = "copy";
$conn = mysqli_connect($dbhost,$dbuser,$dbpass,$db);
?>
submit.php
<?php
include 'connection.php';
$foodA = $_POST['foodA'];
$foodB = $_POST['foodB'];
$foodC = $_POST['foodC'];
$foodD = $_POST['foodD'];
$foodE = $_POST['foodE'];
if(!$_POST['submit']) {
echo "please fill out the form";
header('Location: select.html');
}
else {
$sql = "INSERT INTO remove(foodA, foodB, foodC, foodD, foodE) VALUES (?,?,?,?,?);";
$stmt = mysqli_prepare($conn, $sql);
mysqli_stmt_bind_param($stmt,"sssss",$foodA,$foodB,$foodC,$foodD,$foodE);
mysqli_stmt_execute($stmt);
echo "User has been added!";
header('Location: select.html');
}

<option value="foodA">foodA</option>
<option value="foodB">foodB</option>
<option value="foodC">foodC</option>

You need to name the <select> so you can use the data.
name="food[]"
Like this
<select multiple="multiple" name="food[]" class="options" id="text area" >
<option value="foodA">foodA</option>
<option value="foodB">foodB</option>
<option value="foodC">foodC</option>
<option value="foodD">foodD</option>
<option value="foodE">foodE</option>
</select>
Then if you want the value to be 0 or 1, depending on selected or not, you can use the following to replace this:
$foodA = $_POST['foodA'];
$foodB = $_POST['foodB'];
$foodC = $_POST['foodC'];
$foodD = $_POST['foodD'];
$foodE = $_POST['foodE'];
to
$foodA = 0;
$foodB = 0;
$foodC = 0;
$foodD = 0;
$foodE = 0;
foreach ($_POST['food'] as $value) {
if($value == 'foodA')
$foodA = 1;
if($value == 'foodB')
$foodB = 1;
if($value == 'foodC')
$foodC = 1;
if($value == 'foodD')
$foodD = 1;
if($value == 'foodE')
$foodE = 1;
}
You need to name your select with name=food or something so it will be in $_POST['food']. Each option in the select does not show up in $_POST, only what is selected will be in the name of the select. Each option is not it's own thing.
<select multiple="multiple" name="food" class="options" id="textarea" >
<option value="foodA">foodA</option>
<option value="foodB">foodB</option>
<option value="foodC">foodC</option>
<option value="foodD">foodD</option>
<option value="foodE">foodE</option>
</select>
When you save the data it will have:
$_POST['food'] with the value of 'foodA' if multiples, it will be 'foodA, foodB'
