Compare date/time from form to dates/times in database - php

Question

UPDATE
I edited my code, so now the time is checked correctly:
while($row = mysqli_fetch_array($result)){
$rid = $row['roomid'];
$begin = $row['start'];
$bval = strtotime($begin);
$einde = $row['end'];
$eval = strtotime($einde);
$staco = strtotime($start); //starttime posted from form
$endco = strtotime($end); //stoptime posted from form
$abegin = array(sta => $bval);
$aeinde = array(sto => $eval);
// print_r($abegin);
// print_r($aeinde);
foreach($aeinde as $sto) {
if($staco <= $sto) {$checksto = 1;}
else {$checksto = 0;}
}
foreach($abegin as $sta) {
if($endco <= $sta) {$checksta = 1;}
else {$checksta = 0;}
}
if($checksta == $checksto) {$ok = 1;} else {$ok = 0;}
print_r($ok);
}
}
}
So now: how do I check if $ok contains one or more 0's (don't book the room) or all 1's (book the room).
$roomstate = array(state => $ok) results in more than one array:
Array ( [state] => 0 ) Array ( [state] => 1 ) Array ( [state] => 1 )
I'm doing something wrong, because I think it should be possible to get all the different $ok's in one array and then
if(in_array(0,$roomstate)) { echo "Do not book";} else {$bookitsql = "INSERT INTO reservations ...";}
UPDATE: There is a flaw in my original logic to check availabilty with the rooms that needs to be solved first: now the rooms are not checked correct, so it is impossible to answer this question since the correct data is not displayed. My apologies.
For a system that books rooms I need to check with a new booking if the room is already is booked at the moment. The booking works with a form, and then it compares the results from the form with the content in the database for that room on that date.
while($row = mysqli_fetch_array($result)){
$rid = $row['roomid'];
$begin = $row['start'];
$bval = strtotime($begin);
$staco = strtotime($start);
$einde = $row['end'];
$eval = strtotime($einde);
$endco = strtotime($end);
$abegin = array(sta => $bval);
$aeinde = array(sto => $eval);
foreach($abegin as $sta) {
if($staco $checksta,checkstop => $checksto);
print_r($meh);
}
BetterQuestion:
Now I get `$staco` and `$endco`, which are the start and stoptime from the form.
I also get `$sta` and `$sto`, which are multiple start and stoptimes from the database.
Example:
existing reservations:
sta sto
1: 0800 0959
2: 1130 1259
So now when I get `$staco = 1000` and `$endco = 1114` it doesn't check right.
It only works if the new reservation is later than all the other reservations in the database. How can I solve this?

Answer 1

Your Target Pseudocode shows that you want it all be 0. $meh is an Array.
So what you do now is using a foreach on $meh and then Mark it as Occupied as soon as 1 appears. if this doesnt happen, you can assume that $meh is free, and do you Booking.
$roomState = 0;
foreach($meh as $mehValue){
if($mehValue == 1){
$roomState = 1;
}
}
if($roomState == 1){
print_r("room is occupied");
} else {
//insert stuff
}

Took a different approach, by checking date in my sql-statement.
So, the form posts $start and $end (when the users wants to make a reservation).
Now my code looks like this (and it looks ok, I think):
//form and other errormessages like username==0; $start>$end etcetera
else {
$reservationsql = "SELECT * FROM reservations WHERE roomid = '$roomid' AND ('$start' between start AND end) OR ('$end' between start AND end) OR ('$start' >= start AND '$end' <= end) OR ('$start' <= start AND '$end' >= end)";
$result = mysqli_query($link,$reservationsql) or die(mysql_error());
$num = mysqli_num_rows($result);
if($num>0) {"Error: room already booked at that moment";}
else {//$query = "INSERT INTO ..."}
}
}mysqli_close();
Thanks for all the help here and to think along with me.
