How do you Pass an Arrary from HTML --> PHP--> PostgreSQL fucntion.

So,

I have an HTML page with a from in it that calls a PHP CGI when the user hits submit. In the form is a select box with a size="5" multiple name="Key" statement.

phpinfo() shows that his is properly passing the select as Key[] to the PHP CGI . An I can get the data $_POST('Key') and process it in the PHP program.

Where my problem starts is trying to pass the Array of keys to a PostgreSQL function through a pg_prepare / pg_execute combination.

$return_cde = pg_prepare($conn, "SendKeys", 'select web.sendKeys($1, $2, $3)');
.....
$return_cde = pg_execute($conn, "SendKeys", array($_POST('Pin'), $userData, $current_user->user_login));

Open in new window

I have tried changing the prepare and execute a dozen different ways an received a dozen differ errors.

The PostgreSQL function looks like this --

CREATE OR REPLACE FUNCTION web.sendKeys(web_targets_  integer[], web_test_ text, web_user_ text) RETURNS integer As
$BODY$
DECLARE
    value  integer := NULL;

Open in new window

TIA -- Fir any direction anyone can offer --

Could your provide more code from your html form, php to parser $_POST with key array and all PostpreSQL code ?

I don't find any "?" character in your question post so I guess you need PostpreSQL and PHP tutorial at
this http://www.designmagick.com/article/9/Starting-Out/Adding-data-to-your-database, Right ?

Hope understand your question completely .If not, pls pt it out and write it in detail

Duncan,

First off my php is runinng as a result of a form post not embedded in the html..

So ---
<form action="/cgi-bin/xxxicgi.php" method="post" name="FrontPage_Form1" id="pagemsg" onsubmit="return autocomplete="off" FrontPage_Form1_Validator(this)">

<select id="targetGroups" class="targetSubselect" size="5" multiple name="Key[]" width="40" style="width: 400px">

==============================================================================================

The php cgi has no problem with the array Key

$mySelected=$_POST['Key']
echo "<br>You chose:<br>\n";
foreach ($mySelected as $item)
echo $item."<br>\n";

But when I try to pass the array key to to the PostgreSQL function I get various errors depending on how and where I place the brackets or casts. But nothing seems to work ..

----------------------------------

pg_execute has error, right ? if so, variable passing into web.sendKeys is matched or confilict.

and pg_prepare is no any error at all ?

Please put more echo statement to find out each code is error first

Okay,

Get this --

userKey is array
userMsg is string
user_Login is string

Warning: pg_execute() [function.pg-execute]: Query failed: ERROR: array value must start with "{" or dimension information in /home/dxxxxxxxxx/public_html/xxxxxxxx/cgi-bin/xxxxcgi.php on line 87

$return_cde = pg_execute($conn, "SendKeys", array($userKey, $userMsg, $current_user->user_login));

duncanb7

COuld you put $current_user->user_login as variable first ? something like that

$a=$current_user['user_login'] //example only
echo $a //to see that is what you want
and put it into pg_execute if okay

The 'pg_execute' page only shows 3 parameters and your statement above has 5.

Dave,

The pg_execute has 3 and the statement has 3 .. The connection, and the Reference and the array() of values to be passed. The problem is that the first element of the array is also an array. I think thinking I need to unnest it and pass it that way..

Duncan,

I am passing (or at least trying to) array(array, string, string) which is what the PostgreSQL function wants. Changing the order kind of makes a mess of some documentation and standards in a function that has been used for years within the postgresql database. Are you suggesting array(text, text, array) will make a difference ?

duncanb7

Just think about the input "->" is okay or not ,

Could you put the exact value into put pg_execute() to test pg_execute is okay on sql database ?
PostpreSql sometimes have different declaration writing syntax tolerance from mysql or other sql

I mean try simple example first and it will help to narrow down the bug,

Okay,

So in this case it appears to have passed (Array, Text String, Text String) according to the tail on the postgreSQL system..

               $userMsgE = pg_escape_string($userMsg);
               $userLoginE = pg_escape_string($current_user->user_login);

               $return = pg_query($conn, "select web.sendKeys($userKey, $userMsgE, $userLoginE)");

Open in new window

ERROR: syntax error at or near "," at character 26
STATEMENT: select web.sendKeys(Array, ergewgrewgewgwerg / XXX, JSXXXXXX)
