Hello,

I have a question. How would I go about passing a variable by appending it to a URL (ie. page.php?action=variable), through a form on an HTML page? Finally, I need the page to pop-up too.

So, the user puts the variable's info into a text form field, presses the button, then a new smaller window pops up with the info. Do I need to use a session for this? Or is there an easier way?

Any help would be greatly appreciated.

Thanks!

I tried this:

<input type="submit" value="Get Quote" onClick="window.open('quote.php?<?php echo $tickersymbol;?>')">

And nothing in the form. This doesn't echo it, and if I include it in the form action, then it redirects the user from the page, not just a popup window... any ideas?

Try...

<form name="test">
<input type="text" name="symbol" />
<input type="button" onclick="window.open('http://www.yoursite.com/page.php?symbol='+document.test.symbol); " />
</form>

hope this turns out in the page :)

Works great, thanks!

One other question...

I'm trying to parse a CSV document. I can load the CSV document into an array using fread (to $read); but my question is, how do I read more than one line? For the first row, I use $read[column1], $read[column2], etc., but how would I go about checking a different row?

Again, thanks for any help!

$file = file('file.csv');
foreach ($file as $line) {
$read = split(',', $line);
blah
}

Ok, how would I pull data from a cell then? $read[row,column]? Sorry, I'm new to parsing CSV files in PHP...

Thank again!

I sure there are 1001 ways, but see this one works for you:


<?
$my_array = file("call.csv");

foreach($my_array as $line){

$row = explode(",",$line);
foreach($row as $col) {
echo "$col ";

}
echo "\n";
}

?>

Thanks for replying - I tried that, but I can't seem to get it to work right (probably a mistake I am making)...

Basically, what I'm trying to do is perform calculations based on certain fields within the CSV. So, for example, add the data in row5/column2 to row6/column2.

When I do the calculation on one row, I can just use $read[2] and add it to $read[3], for example. Is there a way I can pin-point locations like this using the same basic command - for example, $read[column,row]? I think that's what artofmobile was getting at, but I can't seem to get it to work - can someone give me an example that will add two fields from two seperate rows?

Again, thanks for the help!

I think this is what you want:



<?
$my_array = file("call.csv");

$values=array();
foreach($my_array as $line){

$row = explode(",",$line);
$one=array();
foreach($row as $col) {
echo "$col | ";
array_push($one,$col);

}
array_push($values,$one);
echo "\n";
}
$find=$values[1];
echo "$find[2]\n";

$find=$values[1][2];

echo "$find\n";

Thanks for the reply. I tried just putting in what you had, and replacing the CSV with the CSV I am using, and adding in my variables:


<?

$monthStart = date("M") - 1;
$dayStart = date("D");
$yearStart = date("Y");
$monthEnd = date("M");
$dayEnd = date("D");
$yearEnd = date("Y");

$my_array = file("http://ichart.finance.yahoo.com/table.csv?s=$tickersymbol&a=$monthStart&b=dayStart&c=$yearStart&d=$monthEnd&e=$dayEnd&f=$yearEnd&g=d&ignore=.csv");

$values=array();
foreach($my_array as $line){

$row = explode(",",$line);
$one=array();
foreach($row as $col) {
echo "$col | ";
array_push($one,$col);

}
array_push($values,$one);
echo "\n";
}

$find=$values[1];
echo "$find[2]\n";

$find=$values[1][2];

echo "$find\n";

?>


Here's the result of that code: http://www.chartsetups.com/beta/swing.php?tickersymbol=drl.

Can you show me an example of how I could add, for example, two fields? Let's say from these two rows,

| 11-Mar-05 | 39.27 | 39.43 | 38.51 | 38.60 | 935000 | 38.60 |
| 10-Mar-05 | 38.00 | 39.50 | 37.85 | 39.27 | 2084600 | 39.27 |

I want to add the 39.27 and 38.00 and print the result... how would I go about doing this?

Again, sorry if I'm a little slow at this - my first time working with CSV.

Thank you so much for the help so far!!

If it is always the second column, then it will be:


<?
$my_array = file("call.csv");

$final=0;
foreach($my_array as $line){

$row = explode(",",$line);
$final+=$row[1];
}

echo "$final\n";
?>

Ok, I think I got it now. Thanks for your help!
