multiple values capturing

jonsof

I have a form which contains a select option.

So i use the multiple attribute in order to have much more values than one, on each occasion.

So how can i recieve all these values which are being posted?

Yes, but i want to take all the values from the selected rows.

If i select 3 rows i want their values
If i select 10 rows i want their values too!

stolzyboy

yes, when you use whatever[], that creates an array wherever you post the page to, so you can use a for loop to loop through the array and echo the values to the screen

<form action="<? echo $PHP_SELF ?>" method=post>
<select name="john[]" multiple>
<option value="1">55
<option value="2">55
<option value="3">55
<option value="4">55
<option value="5">555575757
<option value="6">555575757
<option value="7">555575757
<option value="8">555575757
<option value="9">555575757
<option value="10">555575757
<option value="11">555575757
</select>
<input type=submit name=submit value=submit>
</form>

i put

$i=0;
foreach($_POST[john] as $v) {
    echo "$_POST[john][$i] => $v<br>";
    $i++;}

But it didn;t work 🙁
Where is my fault?

stolzyboy

try this....you may need to use $_POST for vars instead, but i think you will get the idea

<?
for ($i = 0; $i < count($whatever); $i++) //where $whatever was the form name of the select on previous page 
{ 
echo $whatever[$i]<br>;
} 
?>

jonsof

i put

for($i=0;count($POST[john]);$i++) {
echo $POST[john]."<br>";}

but an endless loop generated 🙁🙁 and it was displaying Array on each line!

stolzyboy

are you sure you have to use $POST? if so try setting your $POST[john] equal to $whatever, the do what i suggested

jonsof

i put

<?
for($i=0;$i<=count($_POST[john]);$i++) {
echo $_POST[john][$i]."<br>";}
?>

and it worked as i expected, ultimately!

stolzyboy

good, glad you got it to work 🙂

jonsof

Ok, now the point is how can i set more than one row as SELECTED??. Let's say for an edit page.

stolzyboy

well for that you will have to query the database and go through a while loop, then do an if statement to check if there is a value, if there is you can simply echo selected in the option tag, simple as that, let me know if you need help
