Gud morning to all!

I'm new to this forum and I hope somebody could help me about arrays.

I 'am not gud on explaining things so please try to understand.

my problem is, i want to keep the value of my two dimensional array on a form.

for example..

 

PAGE1.PHP

$nodep = 2;
// ' this part should also be array, right?but how?
$name = $_POST['name'];
$age = $_POST['age'];
$yr = $_POST['yr'];
$school = $_POST['school'];

<form method='post' action='page2.php'>
for($i=1;$i<=$nodep;$i++)
{
   for($j=1;$j<=4;$j++)
   {
     echo"<input type='text' name='name[$i][$j]' value='i don't know what to put here to restore my value from page2.php'>"; $j++;
     echo"<input type='text' name='age[$i][$j]' value='i don't know what to put here to restore my value from page2.php'>"; $j++;
     echo"<input type='text' name='yr[$i][$j]' value='i don't know what to put here to restore my value from page2.php'>"; $j++;
     echo"<input type='text' name='school[$i][$j]' value='i don't know what to put here to restore my value from page2.php'>"; $j++;
   }
}
<input type='submit' value='go to page2'>
</form>

 

PAGE2.PHP

$nodep = 2;
// ' this part should also be array, right?but how?
$name = $_POST['name'];
$age = $_POST['age'];
$yr = $_POST['yr'];
$school = $_POST['school'];

<form method='post' action='page1.php'>
for($i=1;$i<=$nodep;$i++)
{
   for($j=1;$j<=4;$j++)
   {
      echo" $name[$i][$j]? "; $j++;
      echo" $age[$i][$j]? "; $j++;
      echo" $yr[$i][$j]? "; $j++;
      echo" $school[$i][$j]? "; $j++;
   }
}
<input type='submit' value='go to page1'>
</form>

A couple of points...

 

1. What is your data when you say this ... 'i don't know what to put here to restore my value from page2.php'?

 

2. Are you intentionally incrementing this?

echo"<input type='text' name='name[$i][$j]' value='i don't know what to put here to restore my value from page2.php'>"; $j++;

 

3. If you are trying to retrieve an array with what you have try this...haven't tested it though

 

<?php
for($i=1;$i<=$nodep;$i++)
  for($j=1;$j<=4;$j++)
  {
    $name[$i][$j] = $_POST['name[' . $i . '][' . $j .'];
    $age[$i][$j] = $_POST['age[' . $i . '][' . $j .'];
    $yr[$i][$j] = $_POST['yr[' . $i . '][' . $j .'];
    $school[$i][$j] = $_POST['school[' . $i . '][' . $j .'];
  }
?>

 

4. You don't really need a $_POST statement on your form (The one sending) unless you recieve it from prior pages too.

 

5. Use php tag when you are on your php section .... use a separate file or whatever ... just dont forget the tag

<form method='post' action='page2.php'>
<?php
for($i=1;$i<=$nodep;$i++)
{
   for($j=1;$j<=4;$j++)
   {
     echo"<input type='text' name='name[$i][$j]' value='i don't know what to put here to restore my value from page2.php'>";
     echo"<input type='text' name='age[$i][$j]' value='i don't know what to put here to restore my value from page2.php'>";       
     echo"<input type='text' name='yr[$i][$j]' value='i don't know what to put here to restore my value from page2.php'>";
     echo"<input type='text' name='school[$i][$j]' value='i don't know what to put here to restore my value from page2.php'>";
   }
}
?>

 

6. Do you really want to display your result on a form when you recieve it?

7. You don't use double qoutes  < " > when trying to display the value of a variable

 

<?php
for($i=1;$i<=$nodep;$i++)
   for($j=1;$j<=4;$j++)
   {
      echo $name[$i][$j];
      echo $age[$i][$j];
      echo $yr[$i][$j];
      echo $school[$i][$j];
   }
}
?>

 

Work this out section first dude.

to me your best bet is to use sessions

 

Page1.php

<?php
session_start();

//init vars
for($i=1;$i<=$nodep;$i++)
{
   for($j=1;$j<=4;$j++)
   {
     $name[$i][$j] = "cell ".$i."-".$j;
     $age[$i][$j] = "cell ".$i."-".$j;
     $year[$i][$j] = "cell ".$i."-".$j;
     $school[$i][$j] = "cell ".$i."-".$j;
   }
}

//set session values
$_SESSION['name'] = $name;
$_SESSION['age'] = $age;
$_SESSION['year'] = $year;
$_SESSION['school'] = $school;

<form method='post' action='page2.php'>
<input type='submit' value='go to page2'>
</form>
?>

 

 

page2.php

<?php
session_start();

$name = $_SESSION['name'];
$age = $_SESSION['age'];
$year = $_SESSION['year'];
$school = $_SESSION['school'];

for($i=1;$i<count($name);$i++)
{
   for($j=1;$j<=4;$j++)
   {
     echo $name[$i][$j]." ".$age[$i][$j]." ".$year[$i][$j]." ".$school[$i][$j]."<br>";
   }
}

?>
