little help with array

[sheriff]

hi all !

 

I have a textfield like:

 

<input type="text" name="cant[]">

 

on the next page i have 10 textfields like this .. so i have an $cant array.

 

how can I list the value of them from the array ?

with foreach  I suppose but how ?

 

Thanks and sorry for the beginner question!

 

[trq]

<?php

  if (isset($_POST['cant'])) {
    foreach($_POST['cant'] as $cant) {
      echo $cant."\n";
    }
  }

?>

[jitesh]

<?php
echo "<pre>";
print_r($_POST['cant']);

//You can use foreach
foreach($_POST['cant'] as $key => $value){
       echo $key ."---".$value;
}
//Or you can use for
for($i=0;$i<count($_POST['cant']);$i++){
     echo $_POST['cant'][$i]; 
}
?>

little problem ...

 

this textfield is in a table what is generated by php from mysql.

 

after is generated, i enter in this textfield  numbers what is the quantity of each product.

 

the data is sent by the script you tell'd me, but only the last number in the table.

 

 

exemple:

 

<table bgcolor="#000000" cellpadding="1" cellspacing="1" width="78%">
<tr>
    <td width="28%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>Nume</strong></font></td>
    <td width="60%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>Descriere</strong></font></td>
    <td width="5%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>UM</strong></font></td>
    <td width="7%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>Cant</strong></font></td>
</tr>
<tr>
    <td bgcolor="#DDD7CC"><font size="3">product 1</font></td>
    <td bgcolor="#DDD7CC"><font size="3">size and stuff</font></td>
    <td align=center bgcolor="#DDD7CC"><font size="3">buc</font></td>
    <td align=right bgcolor="#DDD7CC"><font size="3"></font>3</td>
</tr>
<tr>
    <td bgcolor="#DDDAD4"><font size="3">product 2</font></td>
    <td bgcolor="#DDDAD4"><font size="3">size and stuff</font></td>
    <td align=center bgcolor="#DDDAD4"><font size="3">buc</font></td>
    <td align=right bgcolor="#DDDAD4"><font size="3"></font>3</td>
</tr>
</table>

    <td width="28%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>Nume</strong></font></td>

    <td width="60%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>Descriere</strong></font></td>

    <td width="5%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>UM</strong></font></td>

    <td width="7%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>Cant</strong></font></td>

</tr>

<?php foreach($_POST['cant'] as $key => $value){ ?><tr>

    <td bgcolor="#DDD7CC"><font size="3">product 1</font></td>

    <td bgcolor="#DDD7CC"><font size="3">size and stuff</font></td>

    <td align=center bgcolor="#DDD7CC"><font size="3">buc</font></td>

it's work now, but because I already have a foreach he double the table,

 

if(isset($_POST)){

          if(count($_POST['check'])){

            $list_selected = "";

            foreach($_POST['check'] as $key => $ids){

                  $list_selected .= $ids .",";

            }

foreach($_POST['cant'] as $key => $value)

            $list_selected = substr($list_selected,0,strlen($list_selected)-1);

            // This will give ur selected ids like this 100,203,125,123

          }else{

            $list_selected = "-1";

          }

}

 

how can i add this ($_POST['cant'] as $key => $value) too ?

 

thanks

[jitesh]

Use For loop

 

for($i=0;$i<count($_POST['check']);$i++){

echo $_POST['check'][$i];

echo $_POST['cant'][$i];

}

[sheriff]

so ...

I have

 

if(isset($_POST)){
          if(count($_POST['check'])){
            $list_selected = "";
            foreach($_POST['check'] as $key => $ids){
                   $list_selected .= $ids .",";
            }
            $list_selected = substr($list_selected,0,strlen($list_selected)-1);
            // This will give ur selected ids like this 100,203,125,123
}
	  }else{
            $list_selected = "-1";
          } 
}

 

how i implement your code ?

if(isset($_POST)){
          if(count($_POST['check'])){
            $list_selected = "";
            for($i=0;$i<count($_POST['check']);$i++){
            echo $_POST['check'][$i];
            echo $_POST['cant'][$i];
}

            $list_selected = substr($list_selected,0,strlen($list_selected)-1);
            // This will give ur selected ids like this 100,203,125,123
}

 

in this way don't work

 

Sorry ... i'm noob

[jitesh]

if count for $_POST['check'] and $_POST['cant'] are same then

<tr>

    <td width="28%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>Nume</strong></font></td>

    <td width="60%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>Descriere</strong></font></td>

    <td width="5%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>UM</strong></font></td>

    <td width="7%" bgcolor="#000000" align="center"><font color="#FFFFFF" size="3"><strong>Cant</strong></font></td>

</tr>

 

<?php for($i=0;$i<count($_POST['check']);$i++){ ?>

<tr>

    <td bgcolor="#DDD7CC"><font size="3">product 1</font></td>

    <td bgcolor="#DDD7CC"><font size="3">size and stuff</font></td>

    <td align=center bgcolor="#DDD7CC"><font size="3"><?php echo $_POST['check'][$i];?></font></td>

    <td align=right bgcolor="#DDD7CC"><font size="3"><?php echo $_POST['cant'][$i];?></font>3</td>

</tr>

<?php } ?>
