PHP - Variables, Loops, And $i=-1

Did PHP a few years ago and for the life of me i can't work out why this doesn't work:

Code: [Select]
for ( $counter2=1; $counter2 < 1000; $counter2++)
{
   for ( $counter1=1; $counter1 < 1000; $counter1++)
   {
      echo "Fixed bug";
   }
}

and yet this does

Code: [Select]
for ( $counter2=1; $counter2 < 100; $counter2++)
{
   for ( $counter1=1; $counter1 < 100; $counter1++)
   {
      echo "Fixed bug";
   }
}


I tested it because I have a rather large amount of data to retrieve from an XML file and i kept receiving errors

I do not have the option that I know of to do a LIMIT 10 in my odbc query.

How can I get it to count the number of while loops and stop at 10?
Code: [Select]
while (odbc_fetch_row($rs))
  {

}

Hello everyone, I've already posted a question trying to resolve my problem,  but I've changed my code so much, I figured it may be best just to post a new thread with a better explanation of what I'm trying to do.  Anyway, here's what I've got:

I have a database with 2 tables: products and reservations.  I have 3 products for now, that can be reserved for any date.  I'm trying to create a page that will display all of the available products for a specific date.  The user selects the date they want to check, and then the code should check their selected date and compare it with the database to display everything that is available on that date.

The database looks like this:

Products Table:

prodid  prodname
01        item 1
02        item 2
03        item 3

Reservations Table:

prodid  resdate
01        02/22/2012
01        02/23/2012
03        02/22/2012

Here is the code that I have now:

Code: [Select]
<?php

$resultres = mysql_query("SELECT `prodid` FROM reservations WHERE `resdate` = '$resdate'") or die (mysql_error());

while ($rowres = mysql_fetch_row($resultres)) {

$resprodid = $rowres[0];

$resultavail = mysql_query("SELECT `prodid` FROM products WHERE `prodid` != '$resprodid'") or die (mysql_error());

while ($rowavail = mysql_fetch_row($resultavail)) {

$prodid = $rowavail[0];

echo $prodid;
                echo $proname;

       }

}

?>

When I select 02/21/2012, I get no results, where I should get all three products as a result, because none of them are reserved on this date.

When I select 02/22/2012, I get a result of these products, in this order: 02, 03, 01, 02.  I should get a result of ONLY 02, because this is the only product that isn't reserved for this date.

When I select 02/23/2012, I get a result of 02 and 03, which in this case would be the correct return, because 01 is the only one reserved for this date.

Any idea what I'm doing wrong here and how to fix it?  Any help is GREATLY appreciated!

Hi All,

and thanks for your help on my last problem now solved.

What i am doing is building a job site and it needs info put in from job seekers regarding their qualifications. Some will have 2 some may have 10 and so on. I need to set up a system that I can put say 10 text boxes in a form that can then go in a MySQL. I only want the filled out boxes to go into the database and not the ones left blank. I have no idea as to where to start with but I think I need to loop through until it comes to the last filled out box but not enter the blank text boxes. i have no idea where to start on this one so if any one has thoughts on this it would be great.

Thank you all for your help in the past.

My goal here is to have it foreach group from the DB it'll create a new frameset with the groupName as the legend and then under each of those it will create another foreach for each of the fields inside of that group that has a enabled value of 0 from the db.  Both queries work correctly. I just get trouble writing foreach loops and I'm not sure how this one is going to work out.

Code: [Select]
<?php

session_start(); // Access the existing session

// Include the database page
require ('../../inc/dbconfig.php');

$defaultCharID = $_SESSION['defaultCharID'];

$styleIDQuery = "
    SELECT
        characters.styleID
    FROM
        characters
    WHERE
        characters.ID = '" . $defaultCharID . "'";
$styleIDResult = mysqli_query ( $dbc, $styleIDQuery ); // Run The Query
$row = mysqli_fetch_array( $styleIDResult, MYSQL_ASSOC );
$styleID = $row[ 'styleID' ];

$biofieldsQuery = "
    SELECT 
        fields.*,
        groups.* 
    FROM 
        fields 
        INNER JOIN groups 
            ON fields.groupID = groups.ID 
    WHERE 
        groups.styleID = '" . $styleID . "' AND fields.styleID = '" . $styleID . "' AND groups.enabled = 0 AND fields.enabled = 0";
$biofieldsResult = mysqli_query ( $dbc, $biofieldsQuery ); // Run The Query
$row = mysqli_fetch_array( $biofieldsResult, MYSQL_ASSOC );
$groupName = $row[ 'groupName' ];

?>

Hi @ all,

I'm building a simpel agenda function for my boss 
Now I've ran in some basic query problems.

First the code:

<?
include_once('../../config/config.php');

$query      =  "SELECT id, bedrijfsnaam, bezoeken FROM clients WHERE actief = 'ja' AND bezoeken > 0 ORDER BY id ASC";
$result     =  mysql_query($query)or die ("Query kon niet worden uitgevoerd");

echo '<table style="border-collapse:collapse;">';

while($row  =  mysql_fetch_assoc($result)){
extract($row);

$bedrijfsnaam = ucfirst($bedrijfsnaam);
$bedrijfsnaam = htmlentities($bedrijfsnaam);

if($rowcount % 2 == 0) {
echo '<tr onMouseover="this.style.backgroundColor=\'#649fbe\'"; onMouseout="this.style.backgroundColor=\'#fff\';" style="background-color:#fff; border-bottom: 1px solid black;">';
} else {
echo '<tr onMouseover="this.style.backgroundColor=\'#649fbe\'"; onMouseout="this.style.backgroundColor=\'#f2f2f1\';" style="background-color: #f2f2f1; border-bottom: 1px solid black;">';
}
        $rowcount ++;


// huidige jaar ophalen
$huidig_jaar = date("Y");

echo'
<td style="width: 313px; font-family: verdana; font-size: 10px; font-weight: bold; min-height: 20px;">'.$bedrijfsnaam.'</td>
<td style="width: 8px; font-family: verdana; font-size: 10px; font-weight: bold;">'.$bezoeken.'</td>
<td style="width: 100px; text-align: center; border-left: 1px solid black;">';

//januari ophalen
$query1      =  "SELECT datum FROM planning WHERE id = '.$id.' AND YEAR(datum) = '$huidig_jaar' AND MONTH(datum) = '01' ORDER BY id ASC";
$result1     =  mysql_query($query1)or die ("Query 1 kon niet worden uitgevoerd");
$num1   =  mysql_num_rows($result1);

echo $num1;

echo'
</td>
<td style="width: 100px; text-align: center; border-left: 1px solid black;">';

//februari ophalen
$query2      =  "SELECT datum FROM planning WHERE id = '.$id.' AND YEAR(datum) = '$huidig_jaar' AND MONTH(datum) = '02' ORDER BY id ASC";
$result2     =  mysql_query($query2)or die ("Query 1 kon niet worden uitgevoerd");
$num2   =  mysql_num_rows($result2);

echo $num2;

echo'

<td style="width: 100px; text-align: center; border-left: 1px solid black;">';

//februari ophalen
$query3      =  "SELECT datum FROM planning WHERE id = '.$id.' AND YEAR(datum) = '$huidig_jaar' AND MONTH(datum) = '03' ORDER BY id ASC";
$result3     =  mysql_query($query3)or die ("Query 1 kon niet worden uitgevoerd");
$num3   =  mysql_num_rows($result3);

echo $num3;

echo'

<td style="width: 100px; text-align: center; border-left: 1px solid black;"></td>
</tr>
';
}

echo '</table>';

?>

In the first query I'll get the id from all the clients in the database, now I want to use that id's in the upcoming query's (WHERE id = '.$id.'), but it allways uses the first id and not all the id's. $num always has the same result.

Can anyone put me in the right direction? Thank you

Sorry for my bad English, I'm dutch, can't help it  I blame my parents...
I hope it's enought information....


Greetings XistenceNL

Man this is really driving me nuts. I can see my array values with echo inside the loop but outside nothing is shown. What am I missing here? If anything it should show the last value in the loop.

while ($x = mysql_fetch_array($query_name,MYSQL_NUM))
{
echo $x[0];
}
echo $x[0];

Hey everyone,

Been a while since I posted.  I hope everyone is doing well.  I've built a couple of for() loops into my program and I'm getting some inconsistent results. 


The first loop I made was just a simple counter looking like this:

Code: [Select]
<select name="event_name">
<?php
for($x = 1; $x <= 50; $x++){
if($x < 10){
echo "<option value=\"$x\">Event 0$x:";
echo "</option>";
}
else{
echo "<option value=\"$x\">Event $x:";
echo "</option>";
}
}
?>
</select>

This code works perfect.  The 1st entry in my drop down list is event 1, then event 2 etc. 


now i have basically the same code on the another selection:

Code: [Select]
<select name="date"
<?php

for($x = 1; $x <= 24; $x++){
if($x < 10){
echo "<option value=\"$x\">0$x:00 EST";
echo "</option>";
}
else{
echo "<option value=\"$x\">$x:00 EST";
echo "</option>";
}
}
?>
</select>

however the generated code on this call starts with a result on 2 instead of 1 giving me 02:00 EST instead of 01:00 EST.  I'm sure I could work around this by declaring some additional variables, but i'm just trying to figure out why i'm seeing different results between these two loops? 

any thoughts?  thanks in advance for your help

Hi all,

I am desperately in need of some help here. I have been troubleshooting these codes for days, and I have posted this similar question quite a couple of times, and there is no answer from anyone... I am really in a bad shape now. Could someone please enlighten me to my problem?

I have created 2 while loops...apparently the 2nd while loop overwrites the 1st while loop record.

Meaning to say...1st while loop generates values of
'Math'
'Eng'
'Chi'
'Sci'
AND store it in $subject_data, createLevelCheckboxes($subject_data, $level_data, 5);

Apparently, the 2nd while loop takes only the last record 'Sci' from $subject_data and continues the looping. Which gives me results like

Level 1
Sci

Level2
Sci

Level3
Sci

I would like to attain something like....
Level 1
Math

Level2
Eng

Level3
Chi

Level4
Sci


Is there any reset which I need to do?



while($data = mysqli_fetch_array($sql)) 
    {
        if($current_level_id != $data['level_id']) 
        {
            $checkboxes .= createLevelCheckboxes($subject_data, $level_data, 5);
            $current_level_id = $data['level_id'];
            $subject_data = array();
        }
        //Add the current record to the $level_data array
        $subject_data[] = $data;
    }

while($data1 = mysqli_fetch_array($sql1)) //Iterate throug the DB results
    {

$checkboxes .= createLevelCheckboxes($subject_data, $level_data, 5);

$level_data = array();

$level_data[] = $data1;

}
    $checkboxes .= createLevelCheckboxes($subject_data, $level_data, 5);

I don't want to have to use two foreach loops.

Code: [Select]
foreach($verify_partners as $verified)
{
        echo $verified;
echo $id;

        if ($verified == $id)
{
?>
<div>
Remove
</div>
<?php
}
}

It prints out as Array6Array6

Hi,

I'm trying to create a script that imports a CSV file but gives the user 3 options:

1. If Exists Update
2. If Exists Keep Both
3. If Exists Ignore New

The keep both is easy, I just insert everything without checks.

However, the other 2 are a little bit tricky (in my mind anyway). I've been told I could create loops and that there isn't any easy way to do this with MySQL. I cannot use ON DUPLICATE KEY because the column that I'm checking cannot be unique (because I have the keep both option).

Is it efficient in PHP to create a loop that checks each row to see if it exists? I'm a little hesitant because the files could be big and I'm not sure how efficient PHP is with CPU and memory resources.

The App I'm making is designed to run in a business environment but it may run on servers that are handling more than one thing (not just web services).

If anyone could give me a few pointers I'd be most grateful.

Thanks.

I'm trying to send an email that has a list created from a while loop to multiple people with an email list created from while loop.  Can someone please help me figure this out?  My brain is fried.  Here's the code that I have:

This is producing an error message that reads: Parse error: syntax error, unexpected '{' in /home/content/29/6879529/html/calhoun/admin/sendreport.php on line 22
Code: [Select]
<?php
include("conf.inc.php");

$result = mysql_query("SELECT `prefix`,`lname`,`email` FROM admin");
$row = mysql_fetch_row($result);

$result2 = mysql_query("SELECT `to`,`from`,`subject`,`message`,`date` FROM allmsgs WHERE reported = 'n' ORDER BY `messid` ASC");
$row2 = mysql_fetch_row($result2);

$cdate = date('m-d-Y');

while ($row = mysql_fetch_row($result)) {

$prefix = $row[0];
$lname = $row[1];
$adminemail = $row[2];
$fullname = "$prefix $lname";

$sendto = "$adminemail";
$emailsubject = "Webstats Report For $cdate.";

while ($row2 = mysql_fetch_row($result2){ // This is line 22.

$to = $row2[0];
$from = $row[1];
$subject = $row[2];
$message = $row[3];
$datetime = $row[4];

$eachmessage = "<p>
<hr width=\"400\">
To: $to<br>
From: $from<br>
On $datetime<br>&nbsp;<br>
$subject<br>$nbsp;<br>
$message
</p>";

}

$emailmessage = "<html>
<body>
$fullname,
<p>
Here is a list of the messages that have been exchanged in the last 24 hours.</p>
$eachmessage
</body>
</html>";

// To send HTML mail, the Content-type header must be set
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

// Additional headers

$headers .= 'From: Webstats <reports@webstats.com>' . "\r\n";

// Mail it
mail($sendto, $emailsubject, $emailmessage, $headers);

}

?>

Here's the code, I had used the query in the header, and now I'm using it to display the links in a table. What happens is that it only returns the first row and not the second third or fourth rows. When it does display the first row, it'll display it a lot of times. Here it is

Code: [Select]
<?php
    if($_GET['place']==addnetwork){
        //display current networks 
        echo "<table border=1>";
        echo "<tr><td>Network Name</td><td>URL</td></tr>";
        
        while ($query1 = mysql_fetch_assoc(mysql_query("select name,url from s_links"))) {
            $networkname = $query1['name'];
            $networkurl = $query1['url'];

            
            echo "<tr><td>$networkname</td><td>$networkurl</td></tr>";
            
        }
        echo "</table>";
    }
?>
