Array insert

[forumnz]

I wish to insert an array into a database. I am really new to this so please help me.

 

Here is my array output:

Array ( [0] => Array ( [qty] => 66 [price] => 5 [item] => ggg [des] => g [acc] => h [tax] => h ) [1] => Array ( [qty] => 66 [price] => 5 [item] => ggg [des] => g [acc] => h [tax] => h ) ) 

 

What can I do?

It's just an array that has 2 other arrays inside it. You would just write 2 loops.

Ok thanks I'm starting to understand. I'm just taking it step by step at the moment, here is what I have:

 

<?php
$e = '[{"qty":66,"price":5,"item":"ggg","des":"g","acc":"h","tax":"h"},{"qty":66,"price":5,"item":"ggg","des":"g","acc":"h","tax":"h"}]';
$d = json_decode($e, true);
$d = (print_r($d));


foreach ($d as $val)
{
echo $val . " ";
}

?>

 

I know the error has something to do with the print_r part, but how can I fix it?

Thanks

 

[Ken2k7]

Why would you set $d to be the value of print_r($d)? Take out that line first.

 

In your foreach, $val is an array, so you'll have to use another loop to go through it. You're almost there.

[forumnz]

Oh I see - getting there!

 

I have this at the moment (snippet):

<?php
foreach ($d as $val)
{

foreach ($val as $arr)
{

$sess_hash = (rand() . rand() . rand() . rand() . rand() . rand() . rand());
$sess_hash = (md5($sess_hash));
$lk = $sess_hash;

mysql_query("INSERT INTO acc_rec_inv (hash_key, inv_key, line_key, item, des, qty, price, acc, tax) VALUES ('$hk', '$ik', '$lk', '$arr')")or die(mysql_error());

}
}
?>

But I get this error:

Column count doesn't match value count at row 1

 

Should I have the query outside of the second array?

[Ken2k7]

Um... you have an INSERT that fills 9 columns, but you only gave it 4 values.

[trq]

You define 9 identifiers in your query yet only 4 values.

[forumnz]

Oops!

 

This is better:

<?php
foreach ($d as $val)
{

foreach ($val as $arr)
{
$in .= "'$" . $arr . "', ";

}
$sess_hash = (rand() . rand() . rand() . rand() . rand() . rand() . rand());
$sess_hash = (md5($sess_hash));
$lk = $sess_hash;

echo $in;
mysql_query("INSERT INTO acc_rec_inv (hash_key, inv_key, line_key, item, des, qty, price, acc, tax) VALUES ('$hk', '$ik', '$lk', '$in')")or die(mysql_error());
}
?>

 

That sort of works, but since I have 2 rows to insert, I have 2 times as much data, so I need to somehow split the $in between ().

 

Is this easy?

Thanks

[Ken2k7]

Edit: oops.. use explode

[trq]

I can plainly see from here that your query won't work. Again, you still have 9 identifiers and only 4 values.

[forumnz]

Thanks for the help. I am almost there. I have the right amount of columns etc..

Just when there is more than one set of data, in adds more fields within the VALUES (here) - that means that there isn't the right amount of columns...

 

Here is what I have:

 

<?php
foreach ($d as $val)
{

foreach ($val as $arr)
{
$in .= "'" . $arr . "', ";
$ina = "('$hk', '$ik', '$lk', " . $in . ")";
$l = array(", )");
$ina = str_replace($l, ")", $ina);
}
$sess_hash = (rand() . rand() . rand() . rand() . rand() . rand() . rand());
$sess_hash = (md5($sess_hash));
$lk = $sess_hash;

echo $ina;
mysql_query("INSERT INTO acc_rec_inv (hash_key, inv_key, line_key, item, des, qty, price, acc, tax) VALUES $ina")or die(mysql_error());
}
?>

 

What do you think? Thanks

[trq]

Given this....

 

]
<?php
$data = '[{"qty":66,"price":5,"item":"ggg","des":"g","acc":"h","tax":"h"},{"qty":66,"price":5,"item":"ggg","des":"g","acc":"h","tax":"h"}]';
$array = json_decode($data, true);

foreach ($array as $innerarray) {
    $sql = "INSERT INTO acc_rec_inv SET ";
    foreach ($innerarray as $k => $v) {
        $sql .= "$k = '$v', ";
    }
    $sql = sustr($sql, 0, -2);
    // at this point in time your query will look like "INSERT INTO acc_rec_inv SET qty = '66', price = '5', item = 'ggg', des = 'g', acc = 'h', tax = 'h'"
    // execute the query.
}

?>

 

Im not sure where your planning on getting 'hash_key, inv_key, line_key' from but you should be able to sort it from here.

[trq]

Of course if your guaranteed that the data will be in the same order within the array at all times you could also have used implode.

 

<?php
$data = '[{"qty":66,"price":5,"item":"ggg","des":"g","acc":"h","tax":"h"},{"qty":66,"price":5,"item":"ggg","des":"g","acc":"h","tax":"h"}]';
$array = json_decode($data, true);

foreach ($array as $innerarray) {
    $sql = "INSERT INTO acc_rec_inv (qty, price, item, des, acc, tax) VALUES ('" . implode("','", $innerarray) . "')";
    // execute query.
}

?>

 

Which would be more efficient.

Hi thorpe

 

Thanks, but for some reason that doesn't work (I fixed the substr), but it isn't inserting anything... WHy could this be?

[trq]

Echo your query to see what it looks like.

 

ps: I don't think there was anything wrong with my call to substr.

[forumnz]

It looks like:

INSERT INTO acc_rec_inv SET qty = '66', price = '5', item = 'ggg', des = 'g', acc = 'h', tax = 'h'INSERT INTO acc_rec_inv SET qty = '66', price = '5', item = 'ggg', des = 'g', acc = 'h', tax = 'h'

 

I guess then I should just change it to complete each query separately?

[forumnz]

Or not? That wouldn't work would it..?

[trq]

Of course you need to execute each query separately, look at where I put the comment about executing the sql.

[forumnz]

Hey thanks this is the query I have at the moment.. The $sql echoed:

mysql_query("INSERT INTO acc_rec_inv SET qty = '66', price = '5', item = 'ggg', des = 'g', acc = 'h', tax = 'h'"); mysql_query("INSERT INTO acc_rec_inv SET qty = '66', price = '5', item = 'ggg', des = 'g', acc = 'h', tax = 'h'");

 

It looks right to me, but how can I actually 'run' the variable instead of echoing it?

[trq]

<?php
$data = '[{"qty":66,"price":5,"item":"ggg","des":"g","acc":"h","tax":"h"},{"qty":66,"price":5,"item":"ggg","des":"g","acc":"h","tax":"h"}]';
$array = json_decode($data, true);

foreach ($array as $innerarray) {
    $sql = "INSERT INTO acc_rec_inv SET ";
    foreach ($innerarray as $k => $v) {
        $sql .= "$k = '$v', ";
    }
    $sql = sustr($sql, 0, -2);
    mysql_query($sql);
}
