Ok so here is the run down. I am trying to make a script for one of my bosses at work. The point is to upload a csv file, convert it to separate fields and store it to a database. Now the upload works fine, the conversion goes smoothly. But when i try to upload it to a database the fields just are not being created. This involves 2 scripts for truncating purposes I will post what is needed. Please any help is appreciated.

 

Note: Im convinced the problem is converting it to a mysql friendly format, as if i pend varchar(blah) to the end of anything it post some of the fields but not all.

 

Script pulling the csv file, converting it, then punches to a relay file.

<?php

REQUIRE 'relay.php';

global $strings, $cmd, $db_name, $db_user, $db_pword, $db_table, $file_temp;

$db_name=$_POST["name"];

$db_user=$_POST["user"];

$db_pword=$_POST["pword"];

$file_temp="supdashboard.csv";

$db_table = "test";

$col=array("bob", "frank");

 

 

//f_mod_table($db_name, $db_user, $db_pword, "csv", "ADD", array("bob varchar(15)"));//$db_name, $db_user, $db_pword, $db_table, $cmd, $col);

//f_store($db_name, $db_user, $db_pword, "csv", array("bob"), array("uhhh"));

//Output a line of the file until the end is reached

$file=fopen($file_temp,"r")or exit("Unable to open file!");

$i=0;

while(!feof($file))

{

$strings[$i]=fgets($file);

str_handle($strings[$i], $i);

$i++;

}

fclose($file);

for($i=0;$i<count($col);$i++)

{

//$col[$i] .=" varbinary(".strlen($col[$i]).")";

/$bob=$col[$i];

/$bob.=" char(15)";

/f_mod_table($db_name, $db_user, $db_pword, $db_table, "ADD", array($bob));

}

//f_delete_table($db_name, $db_user, $db_pword, $db_table);

f_create_table($db_name, $db_user, $db_pword, $db_table);

f_mod_table($db_name, $db_user, $db_pword, $db_table, "ADD", $col);

//f_store($db_name, $db_user, $db_pword, $db_table, $col, $data);

 

//Process the strings to convert into data to be uploaded to the database.

function str_handle($tmp_str, $i)

{

global $col, $data;

if(($i == 0) && (strlen($tmp_str)!= 0 ))

{

$i=0;

$x1=0;

$x2=0;

while(strpos($tmp_str,",") != false)

{

$com=strpos($tmp_str, ',');

$par=strpos($tmp_str, '"');

if(($par < $com) && substr($tmp_str, 0, 1) == '"')

{

$tmp_str = substr($tmp_str,($par+1));

$par=strpos($tmp_str, '"');

$x2=$par;

$col[$i]=substr($tmp_str,$x1, $x2);

$tmp_str = substr($tmp_str,($par+1));

}

else

{

$x2=$com;

$col[$i]=substr($tmp_str,$x1, $x2);

$tmp_str = substr($tmp_str,($com+1));

}

$i++;

}

}

elseif(($i != 0) && (strlen($tmp_str)!= 0 ))

{

$i=0;

$x1=0;

$x2=0;

while(strpos($tmp_str,",") != false)

{

$com=strpos($tmp_str, ',');

$par=strpos($tmp_str, '"');

if(($par < $com) && substr($tmp_str, 0, 1) == '"')

{

$tmp_str = substr($tmp_str,($par+1));

$par=strpos($tmp_str, '"');

$x2=$par;

$data[$i]=substr($tmp_str,$x1, $x2);

$tmp_str = substr($tmp_str,($par+1));

}

else

{

$x2=$com;

$data[$i]=substr($tmp_str,$x1, $x2);

$tmp_str = substr($tmp_str,($com+1));

}

$i++;

}

}

}

 

?>

 

This is the relay script executing the push (i coded it as well but it has tested successfully on many trials when testing with static data) This is just the function in question also.

//Add or delete fields from an existing table

function f_mod_table($db_name, $db_user, $db_pword, $db_table, $cmd, $col)

{

// Connect To Database

$con = mysql_connect($db_name, $db_user, $db_pword);

if (!$con)

{

die('Could not connect: ' . mysql_error());

}

mysql_select_db($db_user, $con);

 

// Counts the size of $col

$num = count($col);

 

// Checks to make sure $cmd is valid

if($cmd != "ADD" AND $cmd != "DROP")

{

echo "Invalid paramater passed into $cmd. Needs to be either \"ADD\" or \"DROP\".";

}

 

//If command is valid perfomrs either add or drop function per number of columns

else if($cmd == "ADD")

{

for($i=0;$i<$num;$i++)

{

$sql="ALTER TABLE $db_table ADD COLUMN $col[$i]";

mysql_query($sql,$con);

echo $col[$i]. " Stored! <br/> ";

}

}

else if($cmd == "DROP")

{

for($i=0;$i<=$num;$i++)

{

$sql="ALTER TABLE $db_table DROP COLUMN $col[$i]";

mysql_query($sql,$con);

}

}

 

// Disconnect from database.

mysql_close($con);

}

 

Again any help would be appreciated its a freelance thing for my boss so hes not going to kill me anytime soon, but i would still like to put it behind me.

sry i typoed *fix below* the 3 lines WERE commented out properly

 

for($i=0;$i<count($col);$i++)

{

//$col[$i] .=" varbinary(".strlen($col[$i]).")";

//$bob=$col[$i];

//$bob.=" char(15)";

//f_mod_table($db_name, $db_user, $db_pword, $db_table, "ADD", array($bob));

}

Sry about the code thing I was not aware. I don't post on forums often. Answering the mad, I have tried declaring it as an array and if it was static data normally you would, but $col is already an array so it double declares it and produces $col to = array when it gets into the relay script.
