Loop Insert from an array?

Loop Insert from an array?

Hello,
I've searched the forums and not seen anything that points out how to take a current single record insert and then modify it IF there are more than one record to insert.

Any pointers on what it would take to modify the Insert behavior to do a loop inserting all values from an array?

Using the latest version of DA, in a PHP environment with MySQL 5.1

code:

// WA Application Builder Insert
if ($_SERVER["REQUEST_METHOD"] == "POST") // Trigger
{
  $WA_connection = $emailList;
  $WA_table = "phplist_user_user";
  $WA_sessionName = "phplist_user_user_id";
  $WA_redirectURL = "";
  $WA_keepQueryString = false;
  $WA_indexField = "id";
  $WA_fieldNamesStr = "email|confirmed|uniqid|htmlemail|subscribepage";
  $WA_fieldValuesStr = "".((isset($_POST["fldEmail"]))?$_POST["fldEmail"]:"")  ."" . "|" . "1" . "|" . md5(uniqid(mt_rand())) . "|" . "1" . "|" . "4";
  $WA_columnTypesStr = "',none,''|none,none,NULL|',none,''|none,none,NULL|none,none,NULL";
  $WA_fieldNames = explode("|", $WA_fieldNamesStr);
  $WA_fieldValues = explode("|", $WA_fieldValuesStr);
  $WA_columns = explode("|", $WA_columnTypesStr);
  $WA_connectionDB = $database_emailList;
  mysql_select_db($WA_connectionDB, $WA_connection);
  if (!session_id()) session_start();
  $insertParamsObj = WA_AB_generateInsertParams($WA_fieldNames, $WA_columns, $WA_fieldValues, -1);
  $WA_Sql = "INSERT INTO `" . $WA_table . "` (" . $insertParamsObj->WA_tableValues . ") VALUES (" . $insertParamsObj->WA_dbValues . ")";
  $MM_editCmd = mysql_query($WA_Sql, $WA_connection) or die(mysql_error());
  $_SESSION[$WA_sessionName] = mysql_insert_id();
  if ($WA_redirectURL != "")  {
    if ($WA_keepQueryString && $WA_redirectURL != "" && isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] !== "" && sizeof($_POST) > 0) {
      $WA_redirectURL .= ((strpos($WA_redirectURL, '?') === false)?"?":"&").$_SERVER["QUERY_STRING"];
    }
    header("Location: ".$WA_redirectURL);
  }
}
?>




Note, I'm also setting a random value to one of the fields and inserting php code as a value was not found as an option in the behavior dialog. No problem as I can remove the quotation marks making it no longer a string but it would be a nice enhancement to also use php functions as insert values.

I can also hand write the insert loop but the reason to use these extensions is the speed of implementation so learning how to loop an array in DA Insert would be of value.

Thanks,

Steve

to create an array loop, you would use a for statement around the insert code:

for($i = 0; $i < sizeof($arrayName); $i++) {
<insert code here>
}

Harder than I thought...

Hello,

I can't seem to get the array posted to the DA Insert Behaviour.

I can print_r the array and see the results present but in the js alert I set in the behaviour the array never shows up. 

<?php require_once("../../Connections/emailList.php"); ?>
<?php require_once("../../WA_DataAssist/WA_AppBuilder_PHP.php"); ?>

<?php 
// WA Application Builder Insert
if (isset($_POST["InsertMe"])) // Trigger
{


echo "<script language=\"JavaScript\">\n";
echo "alert('";
echo '<pre>';
print_r($matches[0]);
echo '</pre>';
echo "we made it this far');\n";
echo "</script>"; 

// loop to allow array of inserts
for($i = 0; $i < sizeof($matches[0]); $i++) {

{
  $WA_connection = $emailList;
  $WA_table = "phplist_user_user";
  $WA_sessionName = "phplist_user_user_id";
  $WA_redirectURL = "";
  $WA_keepQueryString = false;
  $WA_indexField = "id";
  $WA_fieldNamesStr = "email|confirmed|uniqid|htmlemail|subscribepage";
  $WA_fieldValuesStr = "$matches[0]" . "|" . "1" . "|" . md5(uniqid(mt_rand())) . "|" . "1" . "|" . "4";
  $WA_columnTypesStr = "',none,''|none,none,NULL|',none,''|none,none,NULL|none,none,NULL";
  $WA_fieldNames = explode("|", $WA_fieldNamesStr);
  $WA_fieldValues = explode("|", $WA_fieldValuesStr);
  $WA_columns = explode("|", $WA_columnTypesStr);
  $WA_connectionDB = $database_emailList;
  mysql_select_db($WA_connectionDB, $WA_connection);
  if (!session_id()) session_start();
  $insertParamsObj = WA_AB_generateInsertParams($WA_fieldNames, $WA_columns, $WA_fieldValues, -1);
  $WA_Sql = "INSERT INTO `" . $WA_table . "` (" . $insertParamsObj->WA_tableValues . ") VALUES (" . $insertParamsObj->WA_dbValues . ")";
  $MM_editCmd = mysql_query($WA_Sql, $WA_connection) or die(mysql_error());
  $_SESSION[$WA_sessionName] = mysql_insert_id();
  if ($WA_redirectURL != "")  {
    if ($WA_keepQueryString && $WA_redirectURL != "" && isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] !== "" && sizeof($_POST) > 0) {
      $WA_redirectURL .= ((strpos($WA_redirectURL, '?') === false)?"?":"&").$_SERVER["QUERY_STRING"];
    }
    header("Location: ".$WA_redirectURL);
  }
} 
} 
}
?>

The page allows you to specify some page that has email addresses in it then using preg_match_all makes an array of the results. I now need to pass that in the insert loop to the DB.

I'm down to thinking I need pass the array in a $_POST from a hidden field but tests have not worked with that method so I am at a loss.

Any ideas?

your loop should probably be:
for($i = 0; $i < sizeof($matches); $i++) {


the in the insert, reference the array index as $matches[$i]:

$WA_fieldValuesStr = "$matches[$i]" . "|" . "1" . "|" . md5(uniqid(mt_rand())) . "|" . "1" . "|" . "4";

That did not work... I think the problem is just getting the $match array to pass to the DA Insert code.


$match is created within the form
the button is labeled id/name "InsertMe"
and the primary trigger looks for this as referenced by:

<?php 
// WA Application Builder Insert
if (isset($_POST["InsertMe"])) // Trigger
{



But nothing gets inserted nor does any value get shown in the js alert I am using to see if the array is present:


<?php 
// WA Application Builder Insert
if (isset($_POST["InsertMe"])) // Trigger
{

echo "<script language=\"JavaScript\">\n";
echo "alert('";
echo '<pre>';
print_r($matches[0]);
echo '</pre>';
echo "we made it this far');\n";
echo "</script>"; 

// loop to allow array of inserts
for($i = 0; $i < sizeof($matches); $i++) {

{
  $WA_connection = $emailList;
  $WA_table = "phplist_user_user";
  $WA_sessionName = "phplist_user_user_id";
  $WA_redirectURL = "";
  $WA_keepQueryString = false;
  $WA_indexField = "id";
  $WA_fieldNamesStr = "email|confirmed|uniqid|htmlemail|subscribepage";
  $WA_fieldValuesStr = "$matches[$i]"  . "|" . "1" . "|" . md5(uniqid(mt_rand())) . "|" . "1" . "|" . "4";
  $WA_columnTypesStr = "',none,''|none,none,NULL|',none,''|none,none,NULL|none,none,NULL";
  $WA_fieldNames = explode("|", $WA_fieldNamesStr);
  $WA_fieldValues = explode("|", $WA_fieldValuesStr);
  $WA_columns = explode("|", $WA_columnTypesStr);
  $WA_connectionDB = $database_emailList;
  mysql_select_db($WA_connectionDB, $WA_connection);
  if (!session_id()) session_start();
  $insertParamsObj = WA_AB_generateInsertParams($WA_fieldNames, $WA_columns, $WA_fieldValues, -1);
  $WA_Sql = "INSERT INTO `" . $WA_table . "` (" . $insertParamsObj->WA_tableValues . ") VALUES (" . $insertParamsObj->WA_dbValues . ")";
  $MM_editCmd = mysql_query($WA_Sql, $WA_connection) or die(mysql_error());
  $_SESSION[$WA_sessionName] = mysql_insert_id();
  if ($WA_redirectURL != "")  {
    if ($WA_keepQueryString && $WA_redirectURL != "" && isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] !== "" && sizeof($_POST) > 0) {
      $WA_redirectURL .= ((strpos($WA_redirectURL, '?') === false)?"?":"&").$_SERVER["QUERY_STRING"];
    }
    header("Location: ".$WA_redirectURL);
  }
} 
} 
}
?>

create your match array as a session so that it will be available when the form submits

Thanks again Ray it worked...

I'll post the code in case anyone else needs similar methods. There are also a couple cool things like the random ID generation and I also do a setting of DateTime to the DB.

<?php
session_start(); // Start  session
?>

<?php 
// WA Application Builder Insert
if (isset($_POST["InsertMe"])) // Trigger
{

// loop to allow array of inserts
for($i = 0; $i < sizeof($_SESSION['match']); $i++) {

{
  $WA_connection = $emailList;
  $WA_table = "phplist_user_user";
  $WA_sessionName = "phplist_user_user_id";
  $WA_redirectURL = "";
  $WA_keepQueryString = false;
  $WA_indexField = "id";
  $WA_fieldNamesStr = "email|confirmed|entered|uniqid|htmlemail|subscribepage";
  $WA_fieldValuesStr = "".$_SESSION['match'][$i]  ."" . "|" . "1" . "|" . (date('Y-m-d H:i:s')) . "|" . md5(uniqid(mt_rand())) . "|" . "1" . "|" . "4";
  $WA_columnTypesStr = "',none,''|none,none,NULL|',none,NULL|',none,''|none,none,NULL|none,none,NULL";
  $WA_fieldNames = explode("|", $WA_fieldNamesStr);
  $WA_fieldValues = explode("|", $WA_fieldValuesStr);
  $WA_columns = explode("|", $WA_columnTypesStr);
  $WA_connectionDB = $database_emailList;
  mysql_select_db($WA_connectionDB, $WA_connection);
  if (!session_id()) session_start();
  $insertParamsObj = WA_AB_generateInsertParams($WA_fieldNames, $WA_columns, $WA_fieldValues, -1);
  $WA_Sql = "INSERT INTO `" . $WA_table . "` (" . $insertParamsObj->WA_tableValues . ") VALUES (" . $insertParamsObj->WA_dbValues . ")";
  $MM_editCmd = mysql_query($WA_Sql, $WA_connection) or die(mysql_error());
  $_SESSION[$WA_sessionName] = mysql_insert_id();
  if ($WA_redirectURL != "")  {
    if ($WA_keepQueryString && $WA_redirectURL != "" && isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] !== "" && sizeof($_POST) > 0) {
      $WA_redirectURL .= ((strpos($WA_redirectURL, '?') === false)?"?":"&").$_SERVER["QUERY_STRING"];
    }
    header("Location: ".$WA_redirectURL);
  }
} 
} 
}
unset($_SESSION['match']);
?>



note iteration of array :
$_SESSION['match'][$i]


Unique query results added to the session here:

// put results into session as an array
$_SESSION['match'] = (array_unique($matches[0]));
