Re: how to get GET data

In order to achieved this, you, would have to use url re-write (like @Nichito pointed out)

You would still have your username.php which accepts the paramater (hh).

<?php

  $user = $_GET['username']; // Obviously with a bit more security 

  var_dump($user);

  ?>

Hope this helps

Re: How to display php variable in html

It's unclear.

What your suggesting is that $url IS defined as a single variable, but has loads of values.. Almost to say:

$url = "www.google.com, www.yahoo.com";

Which, if this is the case then it's the wrong way to go around things.

I don't get what you mean "echo the variable within HTML" my example did that?

Re: Check value of string as number

You might have to cast the variables, by this, I mean specifically define the variable type. Look at this example:

<?php

    $budget_min = (int) 20; // CAST the variable (int)
    $budget_max = (int) 10; // CAST

    if($budget_min <= 20)
    {
        echo 'The budget is too small!';
    }else{
       echo 'The budget is  fine!'; 
    }

    if($budget_min > $budget_max)
    {
        echo 'The budget is higher than the max budget';

    }
    // Output:
    // The budget is too small!
    // The budget is higher than the max budget
?>

So in terms of your example:

$budget_min = (int) $_POST['budget_min'];

And then you can even be more specific and go:

if(!is_numeric($_POST['budget_min']))
  die("Not a number");

Hope this helps, try clearing up what you want/need?

 }

 // Check if the value entered is numeric
 if(!is_numeric($budget_min))
 {
    // display the error

 }

 if($budget_min >= $budget_max)
 {


 }

?>

Re: How to display php variable in html

It would be this, surely?:

<?php
$url = "something"; // In my php files $url contain multiple values
?>
<html>
<td><input type="text" size="50" value="<?php echo $url; ?>"/></td>
</html>

Ohhhhhhhh!! You're talking about arrays! Apologies!

So you'd have a list of values:

<?php
   $urls = array('www.google.com', 'www.yahoo.com', 'wwww.website.com');
   foreach($urls as $url) {
     echo $url;

   }

   // output
   //www.google.com www.yahoo.com wwww.website.com 
?>

So in theory, it would be something like this:

<?php
   $urls = array('www.google.com', 'www.yahoo.com', 'wwww.website.com');
   foreach($urls as $url) {
     echo '<td><input type="text" size="50" value="' .$url. '"/></td>';

   }
?>

Re: Programming Logic

Hello!!

I don't know if I can offer much help, or, insight to this. You should think of the logic behind Programming as being:

"Anyone can code. Anyone can Google. Does that make you a Programmer? It's understanding the logic and given a task to solve and finding the best concept and solution that best fits the problem." - Phorce, DaniWeb 2012 ;)

I don't understand why they would go down the BASIC route, as it being so old! I converted some code from BASIC to C++ a few months back and the logic/syntax for it was horrible.

As in terms of topics, I imagine a brief overall logic:

OR, AND, NOT, GREATER THAN, LESS THAN (But might not be as basic). I guess it's just to try and make you think about the logic:

"How do I input and manipulate multiple numbers" and then someones logic could be to have a massive list of integer numbers whereas someone elses logic could be to create an array. (I guess)!

Hope this helps a tiny bit :)

Re: Populate a form

Hey, apologies.

You would need to use something like, jQuery/Ajax/Javascript in order to create this kind of functuanlity. You can use PHP to do the processing i.e. ("retriving / displaying data"). But the real-time, none-refreshing element would need to be done in a client-side language.

I guess it would be fairly easy to create it where you can show ("Next {#} Records") for example, as well as shifting through them.

Re: How to avoid var_dump($); output yet get space seperated words in FORM.

Confused..

By using var_dump, it just dumps whatever is stored in a particular varialbe and then outputs it to the screen (or whatever)! In order to display the output, you should just use echo/printf?

<form action="abc.php" method="post">
    <select name="study_class[]" multiple>
    <option value="Class 1">CLASS 1</option>
    <option value="Class 2">CLASS 2</option>
    <option value="Class 3">CLASS 1</option>
    <option value="Class 4">CLASS 2</option>
    </select>
    </form>
    abc.php
    <?php
    #get data
    $study_class=implode(', ', $_POST['study_class']);
    //var_dump($study_class);
    echo $study_class; // this would output it.
    ?>
    <html>
    .
    .
    <P> Study Classes Chosen are: <?php echo $study_class; ?></P>
    .
    </html>

I don't know if that's what you mean! Or whether you want to actually store the result of var_dump inside a variable.

Re: PHP Drop down menu

s among the easiest ways to have multi page CMS up and running in a relatively short space of time. Themes and skins are free in many cases and for beginners it overcomes many of the obstacles that stand in their way. Of course it does replace the need for HTML designers to some extent so maybe that's where you are coming from. Personally I had one site initially which gave me time to earn while I learn. If I had started with HTML or DHTML I may never have had a customised site for a year. But that's just my opinion. Maybe I should'nt be on DaniWeb. It's sounding like a site for programmers and not for those of us who are learning.

@mim2gether DaniWeb is for everyone, which, is what makes it so unique and that's why people come back (And of course stayed loyal!) it's not just for programmers, although, obviously, the majority will be programming since that topic is a major talking point for the visitors. This in mind, you should be here! If not to ask questions for yourself, or to answer questions that are posted by the users but to learn and adapt other coding techniques and standards from other programmers and developers (That's one of the points of programming, right?)!

As for WordPress, and, like you said - Each to their own! I personally developed a website / blog using Wordpress/BuddyPress and found it horrible to develop for. Yeah, I used …

Re: php table

Hello,

It would be a good idea if you atleast tried this yourself, even the smallest attempt would be beneficial since we're not here to do homework.

I don't clearly understand what you want, but, have a look at this:

<?php

    // Accept the users age
    $age = $_POST['age'];

    $half_age = $age / 2; // half the age
    $dble_age = $age*2; // double the age
?>

I'm sure it's not as simple as that.. If you want to increment by 10 each time, then you can do that.. If you want to increment by the half age, or double age.. You can do that as well!

Re: php array and function

Hello,

First of all, I wouldn't put the function there. Make sure that the function is above all of the main code, so like this:

<?php
   function echoArray($theArray)
   {
       $size=count($theArray);
       for ($i=0; $i<=$size; $i++)
       echo "month number " . $i . " is :" .$theArray[$i] . "<br />";
    }

    // rest of PHP code
    // rest of PHP code
?>

(There was a problem with your code inside this function, you were trying to output $months but it does not exist, instead, you need to output $theArray).

The next step is to actually display the months (or in this case, execute the function).

 <?php
       function echoArray($theArray)
       {
           $size=count($theArray);
           for ($i=0; $i<=$size; $i++)
           echo "month number " . $i . " is :" .$theArray[$i] . "<br />";
        }
        $months=array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
        echo echoArray($months);
    ?>

This will now display the months. I don't know how your application works, but, you should be able to adapt these changes inside your code.

I hope this helps you, feel free to ask for further help :) - Phil

Re: Issue with printf the string

No problem :)

Sorry if my answer was a little blunt last night; it was 3am!

Good luck with your project :)

P.S. Thres not a huge difference between echo/printf although I'm sure I read somewhere that echo is faster.

Re: Issue with printf the string

pencils

Here you go..

<?php
$product_name = "pencils";
$product_price= 7.99;
printf( "Product %s will cost %1.1f dollars.",
$product_name, $product_price );
?>

Remember, %s = string. %f = floating point number..

Hope this solves it :)

Re: Automatically create an archive by month and year?

here, I don't know how to get PHP to build a list using the data. I could do it manually every time a new month comes up, but that defeats the purpose in my book.

Hello,

Basically (From what I understand) you should have a table/column that populates a list of months, from this month, the form should handle it by a $_GET method. So for example:

yoursite.com/Archive.php?month=january

and the php would be like this:

<?php

  $month = $_GET['month'];

  // rest of php code

 ?>

You can populate the form (list of months) by a query.

Sorry it's not much help, message back if you require any further code snippets!

Re: syntax errors and missing function header

Hello,

First of all..

int main();

Shouldn't have a semicolon, therefore it should just be:

int main()
{

   return 0;
}

You've also declared a function, but, it doesnn't mean it's wrong, you can set the prototype (Especially if your using the function in main, but it's actual functiuanlity is set outside of main).

Also, you seem to be accepting numbers (in a for loop) that only get entered into a single variable.. This isn't right, you need to create an array for the numbers to be stored in, and then pass this array to a function that calculates all of the numbers together. (I think this is how you want the program to work!)

Have a look at this example:

#include <set>
#include <iostream>

using namespace std;

     double atotal(double *theNumbers, int theTotal)
     {
        int total = 0;

        for(int i=0; (i < theTotal); i++)
        {
            total += theNumbers[i];

        }
        return total;
     }

    double daverage(double *theNumbers, int theTotal)
    {
        int total = atotal(theNumbers, theTotal)/theTotal;

        return total;

    }

int main()
{
    int itotal = 0;

    cout << "please enter how many numbers: " <<endl;
    cin >> itotal;
    double* a = new double[itotal];

    cout << "start entering numbers" <<endl;
    for(int i = 0; (i < itotal); i++)
    {
        cin >> a[i];
    }
    // This will display the numbers added together
    cout << "The total sum of the numbers is: " << atotal(a, itotal) << endl;
    cout << "The average of the numbers is: " << daverage(a, itotal) << …

Re: Issue with printf the string

printf( "Product %f will cost %1.1f dollars.",
$product_name, $product_price );

Can't you just echo it?

<?php
$product_name = (string) "pencils";
$product_price= 7.99;

echo "Product $product_name will cost $product_price";
?>
