a while() within a while()


Recommended Posts

Hi guys, 


I am trying to create a while condition that would display an output such as: 


"Duty: 1234, = Dep: 01:00, End: 03:35

code1, code4, code5"


The problem I am having is instead of echoing the first line once, with my while statements the first line will echo as many times are there are codes associated with it that I am trying to output from another mysql table. 


Have a look below and you will see what I mean! My output at the moment looks like:


"Duty: 1234, = Dep: 01:00, End: 03:35


Duty: 1234, = Dep: 01:00, End: 03:35


Duty: 1234, = Dep: 01:00, End: 03:35

$sql = "SELECT * FROM calendar WHERE Duty = '$duty' AND BeginTime = '$begintime' AND EndTime = '$endtime'";
$result = mysqli_query($cxn,$sql)
	or die ("Can't execute query.");

while($row=mysqli_fetch_assoc($result)) {
	echo 'Duty: '.$row['Duty'].' = Dep:'.$row['BeginTime']. ', Land:'.$row['EndTime'].'<br />';

	$sql1 = "SELECT * FROM users WHERE Code = '{$row['Code']}'";
	$result1 = mysqli_query($cxn,$sql1)
		or die ("Can't execute query1.");

	while($row1 = mysqli_fetch_assoc($result1)) {
		echo $row1['Rank'].': '.$row['Code'].'</br>';

Have you verified that you data reflects what you think is supposed happen? It looks to me like there are three separate calendar entries, each with a different code. And your code shows a "Rank: Code" format that isn't shown in your output. Which does have stray commas in the Duty lines.


Ha, ha, "duty".
