PHP - [php] While Loops In Mysql

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

Hi guys   I just wanted to make a short post and talk about an issue im having and maybe get some advice. I know that loops aren't that hard to grasp and I shouldn't be having this much trouble understanding them but im just not getting it. I dont really know how to explain it but loops (like looping through mysql in an update statement) is foren to me and i was wondering if anyone had any advice for maybe learning them or maybe something im just over looking or maybe some good tutorials.

I really want to get them down and start using them in scripts i right but im getting so frustrated because i constantly hear how easy they are and im just not getting it.

if i wasn't clear please let me know and ill try to explain more clearly

thanks guys

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!

i have been given this task in in uni. i was wondering it some one would be so kind to help me with it. all i have so far is this
<?php
for($x=1; $x<=3; $x=$x+1) {
print  "$x <br>";
}
 if ($x== "A") {
}




?>

the task is below



Generate a number between 1 & 3
If 1 then assign A, If 2 then assign B, If 3 then assign C
Add to a wordstring (using string concatenation with .)

We need 3 letters generated to give a 3 letter word

For loop (3)
Generate a number between 1 & 3
If 1 then assign A, If 2 then assign B, If 3 then assign
    C
Add to a wordstring (string concatenation with .)
End loop
Print 3 letter word

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.

i am having issues with my class work.  this needs to start at the $startNum and end with the $endNum and display results in the increments submitted by the html.  I can not get it to print out correctly  it is supposed to say:
The square of $startNum is $square //until it hits the end number and is going up by the correct increments,
It wont go up by any increments and only shows a list if i leave out the increment-----any suggestions??? please i have to keep it very simple since i am just learning-ty

html

</head>
<body>
<h1>Squares</h1>
<p>
<form action = "squares2Boles.php" method = "post" >
<p>Start with:
<input type = "text" size = "5" name = "startNum" />
</p><p>End with:
<input type = "text" size = "5" name = "endNum" />
</p><p>Increment by:
<input type = "text" size = "5" name = "increment" />
</p><p><input type = "submit" value = "Display the Squares" /></p>
</form>
</body>
</html>

my php:

<html>
<head>
<title>Squares</title>
<link rel ="stylesheet" type="text/css" href="sample.css" />
</head>
<body>
<?php
$startNum = $_POST['startNum'];
$endNum = $_POST['endNum'];
$increment = $_POST['increment'];
$square = $_POST['square'];
print ("<h1>SQUARES</h1><hr />");
for ($startNum = $startNum; $startNum <= $endNum;
$startNum = $startNum + $increment)
{ 
$square = $startNum * $startNum;
print ("The square of $startNum is $square<br />");
}
print ("<hr />");
?>

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);

Hi @ all,

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

First the code:

</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

I created the code below and it outputs the following number output:
1111111773526604115551144611337112281111221111345 6789101121111100352004110051100611007110081100221 1003456789101141111100352004110051100611007110081 1002211003456789101151111100352004110051100611007 1100811002211003456789101123111110035200411005110 06110071100811002211003456789101134
Anyways if you look at the code, I need to be able to add the values on a single colony, idcol, with the same type and subtype, btid/stid, generated as the $prod variable. buildings with the same subtype generate the same resource, in this case, several iron mines and a single copper mine are present, but there are also 9 other types of resource buildings. How do I collect on the prods which go together?

Hello, lately I have been having a problem with my simple PHP script. Out of the blue the following script doesnt seem to work properly,
function sanitize_tags($content, $bad_tags = '') {
    foreach ($bad_tags as $tag) {
        $stripped_tags = str_replace($tag, '', $content);
        return $stripped_tags;
    }

    return $content;
}

$contents = "<html>
<head>
</head>

<body>yutu<style>ghghl;kl;<script>hfjhk
</body>
</html>";
$bad_tag = array("<style>", "<script>");

$sanitize = sanitize_tags($contents, $bad_tag);
echo $sanitize;

Basically, when the function is invoked, only the first element in the array is used by the function. It seems like the second+ elements arent even iterated. Why is it only the first element is iterated? I have a feeling its going to be something extremely obvious.

Thanks in advance.

I will start off by saying , I am a NooB. i understand concepts , but have trouble with figuring out the proper way to code thing out. I am trying to use an HTML form that the user can input two numbers, and use those numbers to create a table to be echoed back.

echo "<form action='action.php' method='post' name='columns'>
Enter number of columns and rows to be displayed:<br /> Columns:<input type='text' name='colnums' size=3 maxlength=6 />Rows :<input type='text' name='rownums' size=3 maxlength=6 />
<br /><input type='submit' value='submit' /></form>" ;

This is my form. I have made a loop that will display but not in the fashion i would like it to.


for  ($createColumns=$_POST['colnums']; $createColumns<=10 ; $createColumns++) {      
   echo "<td>" . $createColumns . "</td>"  ;
}

I am looking to write a script that only needs the user input for the number of rows and columns to be displayed.
I think I need a range function or possibly an array for the possible numbers that can be input, but I'm not sure.
The loop I've made has a top limit and an increment that i don't think i need.
If you have any ideas I would greatly appreciate it.

hi

i have a db of tv shows, episodes and descriptions. they are in the db like:

name     | series | episode | description
Friends   | 1       |  1          | example
Friends   | 1       |  2          | example
Scrubs    | 1       |  1          | example

I want to display it this way:

Quote

Friends
Series 1 Episode 1
Series 1 Episode 2

Scrubs
Series 1 Episode 1


cant seem to get it to fully work - it will display it for the first show but not do more than one


thanks for any help

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>";
    }
?>

I know this function will get one result, I suspect foreach is the wrong loop to use,  should I be using a loop at all? Can someone correct me please.

 

public function getSites($site) {
		$sql = "SELECT * FROM website WHERE website_id = ?";
		$stmt = $this->connect()->prepare($sql);
		$stmt->execute($site)
		$siten = $stmt->fetch();
			
		foreach ($siten as $row) {
			$title = $row["website_title"];
			$wname = $row["website_name"];
			$image1 = "header.jpg";
			$metadesc = $row["website_description"];	
			$wurl = $row["website_url"];
			$gtag = $row["website_gtag"];
			$gmap = $row["website_map"];
			$wcss = $row["website_css"];
		}
	}

i am sorry for this reason English is bad
I want to use two nested loops ( while )
Once the model code will loop
