Insert multiple rows into mysql (items separated by comma)

Question

I have a small problem :) I was searching the web but didn\'t find any solutions.

I have a value like this (got it from $_GET[])

tag1, tag2, tag3, tag4

Answer 1

Try this for size: (combining ideas from a number of people who almost got it right).

$values =  array(
                    33=>'tag1'),
                    33=>'tag2'),
                    33=>'tag3'),
                );

$sql = "INSERT INTO table (id, value) VALUES ";
$count=0;
foreach ($values as $id=> $value)
{
    if ($count++ > 0)
        $sql .= ',';
    $sql .= "($id, '$value')";
}
$query = mysql_query($sql, $db);

Answer 2

$id=33;

$tag=$_GET['tag'];
$tag_Split= explode(",", $tag);

$cnt=count($tag_Split);

for($i=0;$i<$cnt;$i++)
{
mysql_query("insert into tag_table(id,tag) 
values ($id, $tag_Split[$i])");
}

Answer 3

Use explode() function to split the string

$tag  = "tag1, tag2, tag3";
$pieces = explode(", ", $tag);

SQL query would be

INSERT INTO myTable VALUES ($pieces[0],$pieces[1],$pieces[2]);

Good Luck!!!

Answer 4

You can do an INSERT INTO with multiple values:

INSERT INTO table (tag) VALUES ('tag1', 'tag2', 'tag3');

Make sure, you properly escape your input (if user suplied) to prevent SQL injection. You can use mysql_escape_string() for this.

Edit: To get these values, you can do:

$values = explode(",", $_GET['your_param']);
foreach($values as $idx => $val) {
  $values[$idx] = mysql_real_escape_string(trim($val));
}

mysql_query("INSERT INTO table (tag) VALUES (".implode(",", $values).");");

Answer 5

I would convert your comma-delimited tags into an array, then loop through the array to do your inserts.

$data_array=explode(",",$tag); // converts tags to an array based on the comma

// loop through each item in the array
foreach($data_array as $one_tag){

// Get rid of the space you have in your tag string
$one_tag=trim($one_tag);

// Do whatever sanitization you need to do to your data, for example...
$one_tag=mysql_real_escape_string($one_tag);

// Insert into the database
mysql_query("INSERT INTO table SET tag='$one_tag'");

}

You can make this more efficient using Prepared Statements, but it kept this example simple.

This will work out according to your result

$tagData = array();
$tagList  = explode(",","tag1,tag2,tag3,tag4");
foreach ($tagList as $key=>$value) {
    $tagData[] = '("' . $key . '", "' . $tagList[$key] . '")';
 }
$query = 'INSERT INTO tags (id,tag) VALUES' . implode(',', $tagData);
echo $query;die;
mysql_query($query);
