PHP - Check If Times Overlap

Hello All,

I have tried to find a solution for this issue for days. The script was working fine until yesterday when all of a sudden I get this warning.

Quote

Warning: imagecreatefrompng(http://domain.com/images/broadcast1.png) [function.imagecreatefrompng]: failed to open stream: Connection timed out in /home/domain/public_html/logo/logo1.php on line 8


line 8 is:
$image_1 = imagecreatefrompng($file_1);
Where
$file_1 = "http://domain.com/images/broadcast1.png";

The exact code is working perfectly fine in a different server I have, both servers are running Centos with PHP5 + GD fully enabled. The image http://domain.com/images/broadcast1.png (~5Kb) is loading very fast when open through a browser.

Please please help me resolve this, I have tried many different things and even uninstall and install GD again but n luck. Thank you so much for your help.

Hi all

I am trying to edit a piece of code to change possible times for a booking system.

This is the code I have:

$count=0;
               for($b=$startTime;$b<$endTime;$b++){
                  if($count==$tempVar2){ $availability .= "</td><td align='left' valign='top'>"; }   
                  if(in_array($b,$reservedArray)){
                     $availability .= $b.":00 ".($b<12?"am":"pm")." - ".($b+1).":00 ".($b+1<12?"am":"pm")." - Booked.<br>";
                  } else {
                  $availability .=$b.":00 ".($b<12?"am":"pm")." - ".($b+1).":15 ".($b+1<13?"am":"pm")."- <input type=\"checkbox\" value=\"".$b."\" name=\"time[]\" ><br>";
                  }
                  $count++;
               }

It gives me the following times:

09:00 am - 10:15 am
10:00 am - 11:15 am
11:00 am - 12:15 am
12:00 pm - 13:15 pm
13:00 pm - 14:15 pm
14:00 pm - 15:15 pm
15:00 pm - 16:15 pm
16:00 pm - 17:15 pm

How can I change it so I can have the following times available:

10:00 am - 10:30 am
10:45 am - 11:15 am
11:30 am - 12:00 pm
12:15 pm - 12:30 pm
etc...

Many thanks for you help
Pete.

Is there a way to put the value of every 15mins into an array starting and finishing at 2 var times

$time1=10.00am
$time2=1.30pm

$timearray=array($time1, and every 15min interval up to but not including $time2)
        eg  $timearray=array(10.00am,10.15am,10.30am..........1.15pm)

Hello PHP Freaks,

I am using a basic payment frame system, and it requires me to pass in a GMT time in this format, in a hidden form.

"YYYYMMDDHHMMSS"

I have found a lot of examples in PHP on how to format the above tag, but what would be the easiest way to generate it as is?
To make things a little more complicated, there are different users in different GMT times, and based on the state they select it needs to + or - hours from the current time to get the GMT time.

The formulas to calculate the results are as follows, just after the best approach in PHP to calculate:

State #1:   CURRENT_TIME + 10 HOURS = GMT TIME (echo as YYYYMMDDHHMMSS) and assign to $GMT_TIMESTAMP
State #2:    CURRENT TIME + 9.5 HOURS = GMT TIME  (echo as YYYYMMDDHHMMSS) and assign to $GMT_TIMESTAMP



What would be the best way to tackle this ? At the moment I have select boxes where the user can pick the state, then click SUBMIT.

Thankyou in advance,

D

Hello,

I am having a heck of a time trying to get time right on my website lol  When a user logs in, they select what timezone they are in (UTC -1,-2,-3,-4,-5,-6....)  Now this is great an all, but with daylight savings time my times are off by one hour in either direction.  How do sites like this get times to work for users so easily?

Thanks!

I've simply set some sessions....

$_SESSION['LoggedIn'] = 1;
$_SESSION['UserID'] = $row["UserID"];

They don't seem to last very long, usually when I close my browser and go back on later, they'll expire. I want them to last permanently unless the user logs out.

How do I do this?

Thanks in advance.

I have a string, and I have a variable

$var = 5;
$str = '<img src="img.jpg" />';


i want to display a $str (the image) $var amount of times (5). how can I do this?

Hi There,

I am trying to use PHP to create a calendar that only show's working days - which are monday to friday.

Is there any way that PHP can return a list of the next 5 working day's dates? For example, if today is Thursday 15th Sept - could it return the numbers 15,16,19,20 and 21?

Thanks
Matt

I have an array of appointment start times throughout a day. All appointments last 30 mins.

I also have a list of times that staff are available to meet these appointment times (can be in any format, array etc.)

I need to ensure the appointment times are fully covered by members of staff.

E.g.
Code: [Select]

$appointmentStart[] = "09:30";
$appointmentStart[] = "10:00";
$appointmentStart[] = "11:00";
$appointmentStart[] = "12:30";
$appointmentStart[] = "13:30";
$appointmentStart[] = "15:00";
$appointmentStart[] = "17:00";

$staffMembers[] = "09:00*12:00";
$staffMembers[] = "13:00*16:00";
$staffMembers[] = "15:00*18:00";

In the above case, no, there are not enough staff members to cover this as nobody works from 12:00 to 13:00. I only really need a yes or no. Don't worry about staff breaks, they never work more than 3 hours each at a time.

Thanks in advance for any help.

Well I'm hoping someone will have some fun with this.
My database has a list of times for a given date, and a schedule for each time. I'm trying to change the input backgrounds for rows between 2 different times. Like this:

8:00   enter some data
8:10   enter some data
8:20   enter some data
etc.
What I want is to change the background color of any input field between say 9:00 and 10:00, but leave everything else white.
I can change the color, just can't figure out how to compare the times.

Here's part of the code:
Code: [Select]
while($row = mysql_fetch_array( $result ))
{


$opentimeID = date("g:i",strtotime(1530)); //not sure if these statements are correct.
$closetimeID = date("g:i",strtotime(1730));
if (strtotime($row['Time']) //...not sure how to finish this statement to compare the time in the database row to $opentime and $closetime.


{
echo "<tr><td>";
echo date("g:i ", strtotime($row[Time]));
echo "</td><td>";
echo "<input type='text' size='20' value= '$row[Player1]' name='player1[$i]'
style ='background-color: #FFFF66;'>";
echo "</td><td>";
echo "<input type='text' size='20' value= '$row[Player2]' name='player2[$i]'
style ='background-color: #FFFF66;'>";
echo "</td><td>";
echo "<input type='text' size='20' value= '$row[Player3]' name='player3[$i]'
style ='background-color: #FFFF66;'>";
echo "</td><td>";
echo "<input type='text' size='20' value= '$row[Player4]' name='player4[$i]'
style ='background-color: #FFFF66;'>";
echo "</td><td>";
echo "<input type='text' size='20' value= '$row[Player5]' name='player5[$i]'
style ='background-color: #FFFF66;'>";
}
else
{
echo "<tr>";
echo "<td>";
echo date("g:i ", strtotime($row[Time]));
echo "</td><td>";
echo "<input type='text' size='20' value= '$row[Player1]' name='player1[$i]'>";
echo "</td><td>";
echo "<input type='text' size='20' value= '$row[Player2]' name='player2[$i]'>";
echo "</td><td>";
echo "<input type='text' size='20' value= '$row[Player3]' name='player3[$i]'>";
echo "</td><td>";
echo "<input type='text' size='20' value= '$row[Player4]' name='player4[$i]'>";
echo "</td><td>";
echo "<input type='text' size='20' value= '$row[Player5]' name='player5[$i]'>";
}

Thanks for any advice!

I only see one "mysql_query($memberquery);"  Yet the record is inserted 4 times when I check the db.  Anyone see why?

Thank you for your time!

Code: [Select]
<?php 
$link_register = 1;
session_start(user);
include("header.php"); 



$firstname      = $_SESSION['firstname'];
$middleinitial  = $_SESSION['middleinitial'];
$lastname      = $_SESSION['lastname'];
$phone      = $_SESSION['phone'];
$email      = $_SESSION['email'];
$street      = $_SESSION['street'];
$city      = $_SESSION['city'];
$state      = $_SESSION['state'];
$categoryArray  = $_SESSION['categoryArray'];
$gender      = $_SESSION['gender'];


$con = mysql_connect("localhost", "root", "");

if (!$con)
{
die("Could not connect: ". mysql_error());
}

//The database is selected with the mysql_select_db() function.
mysql_select_db("hobbyclub", $con);

//put the data insert into a varaible so it can be checked later
$memberquery = "INSERT INTO member (firstname, middleinitial, lastname, phone, email, street, city, state, gender) 
VALUES ('$firstname', '$middleinitial', '$lastname', '$phone', '$email', '$street', '$city', '$state', '$gender')";

// if ($categoryArray){
 // foreach ($categoryArray as $category){
// $categoryString .= "'$".$category."',";
// }
// }
// $categoryquery = "INSERT INTO category (categoryname) VALUES('$categoryString')";
// $categoryquery = "INSERT INTO category (categoryname) VALUES(".$categoryString.")";
 

//insert the data
mysql_query($memberquery);


?>
The commented out block of code is just me trying to figure out how to insert an array into the db.

Are either of these OK depending on circumstance or stupid things I should never do? Is one or the other sensible/idiotic? Is there an obvious 'better' way?   I think all the php tags opening and closing within the DIVs is untidy but it's static HTML therefore if there's a LOT of it it's easier on the server right/wrong?

On the other hand, maybe all the open/close of php tags defeats the object.

I'm applying for a web design apprenticeship (I know, I need one) so I'm trying to appear less stupid as much as make nice php.   Many thanks in advance, I know I'll end up better off by asking here

<?php
 
// php in here

?>
    <div class='content header'>
        <?php include("includes/header.php"); ?>
    </div>
    <div class='content content1'>
        <?php include("includes/intro.php"); ?>
    </div>
    <div class='content content2'>
        <?php include("includes/quals.php"); ?>
    </div>
    <div class='content content3'>
        <?php include("includes/experience.php"); ?>
    </div>
    <div class='content content4'>
        <?php include("includes/hobbies-and-interests.php"); ?>
    </div>
<?php

// More php here

?>

Or this one:

<?php
    print("<div class='content header'>");
        include("includes/header.php");
    print("</div> \r\n <div class='content content1'>");
        include("includes/intro.php");
    print("</div> \r\n <div class='content content2'>");
        include("includes/quals.php");
    print("</div> \r\n <div class='content content3'>");
        include("includes/experience.php");
    print("</div> \r\n <div class='content content4'>");
        include("includes/hobbies-and-interests.php");
    print("</div> \r\n");
?>

I have a form created that seems to work across most devices/connection.. but for some reason some phones, Androids specifically so far, seem to time out when the form is submitted using the mobile network. This has happened on multiple android phones. Doesn't seem to have an issue with iPhones. I also had a problem with a Surface tablet when connected to an android wireless signal.. tethering, the same phone that had the issue.   So what happens is once the form is submitted, it hangs for a while and then it'll say "No data received - Unable to load the webpage because the server sent no data. Reload this webpage Press the reload button to resubmit the data needed to load the page. Error code: ERR_EMPTY_RESPONSE" and then after i refresh, it submits and goes through without a problem. Sometimes it refreshsed by itself after flashing this error and goes through.    Another time, using the Surface Pro, wifi and IE, I got the error "Forbidden" you don't have permission to access /new-window-2.php on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.   You can see an example of one of the forms here - connecttopros(dot)com/windows.php   And some of the code is attached below. I'm lost. I've tried using a different server completely, twice, and it didn't fix the issue, so it must be the way the php is put together?
