Have you every wanted to print out all the data in a MySQL table to a clean looking dynamic HTML table? It is a pretty simple process. In this tutorial we will create a function that can be reused anywhere in your site to dynamicly print the contents of a MySQL table in a clean looking HTML table.
Here is the breakdown:
Here is how to do it step by step:
<?php
include("<---path to MySql connection file--->");
$global_dbh = mysql_connect($hostname, $username, $password)
or die("Could not connect to database");
mysql_select_db($db, $global_dbh)
or die("Could not select database");
This code takes varibles stored in an external file, connects to the database, then selects the database.
function display_db_query($query_string, $connection,
$header_bool, $table_params)
{
// perform the database query
$result_id = mysql_query($query_string, $connection)
or die("display_db_query:" . mysql_error());
// find out the number of columns in result
$column_count = mysql_num_fields($result_id)
or die("display_db_query:" . mysql_error());
// Here the table attributes from the $table_params variable are added
print("<TABLE $table_params >\n");
// optionally print a bold header at top of table
if ($header_bool)
{
print("<TR>");
for ($column_num = 0;
$column_num < $column_count;
$column_num++)
{
$field_name =
mysql_field_name($result_id, $column_num);
print("<TH>$field_name</TH>");
}
print("</TR>\n");
}
// print the body of the table
while ($row = mysql_fetch_row($result_id))
{
print("<TR ALIGN=LEFT VALIGN=TOP>");
for ($column_num = 0;
$column_num < $column_count;
$column_num++)
{
print("<TD>$row[$column_num]</TD>\n");
}
print("</TR>\n");
}
print("</TABLE>\n"); }
This is the first of two functions needed to print the table. The next fuction simpily passes the variables to the first function.
function display_db_table($tablename, $connection,
$header_bool, $table_params)
{
$query_string = "SELECT * FROM $tablename";
display_db_query($query_string, $connection,
$header_bool, $table_params);
}
?>
Next comes the actual HTML of the page (where the functions will be called).
<HTML><HEAD><TITLE>Displaying a MySQL table</TITLE></HEAD> <BODY> <TABLE><TR><TD> <?php //In this example the table name to be displayed is static, but it could be taken from a form $table = "table1"; display_db_table($table, $global_dbh, TRUE, "border='2'"); ?> </TD></TR></TABLE></BODY></HTML>
Hopefully you've learned from this tutorial and will find this code usefull. If you have any questions/comments feel free to post. A working example can be found here.
For your convenience, here is the full file (great for being used in an 'include()' statement at the top of your pages):
<?php
include("<---path to MySql connection file--->");
$global_dbh = mysql_connect($hostname, $username, $password)
or die("Could not connect to database");
mysql_select_db($db, $global_dbh)
or die("Could not select database");
function display_db_query($query_string, $connection, $header_bool, $table_params) {
// perform the database query
$result_id = mysql_query($query_string, $connection)
or die("display_db_query:" . mysql_error());
// find out the number of columns in result
$column_count = mysql_num_fields($result_id)
or die("display_db_query:" . mysql_error());
// Here the table attributes from the $table_params variable are added
print("<TABLE $table_params >\n");
// optionally print a bold header at top of table
if($header_bool) {
print("<TR>");
for($column_num = 0; $column_num < $column_count; $column_num++) {
$field_name = mysql_field_name($result_id, $column_num);
print("<TH>$field_name</TH>");
}
print("</TR>\n");
}
// print the body of the table
while($row = mysql_fetch_row($result_id)) {
print("<TR ALIGN=LEFT VALIGN=TOP>");
for($column_num = 0; $column_num < $column_count; $column_num++) {
print("<TD>$row[$column_num]</TD>\n");
}
print("</TR>\n");
}
print("</TABLE>\n");
}
function display_db_table($tablename, $connection, $header_bool, $table_params) {
$query_string = "SELECT * FROM $tablename";
display_db_query($query_string, $connection,
$header_bool, $table_params);
}
?>
<HTML><HEAD><TITLE>Displaying a MySQL table</TITLE></HEAD>
<BODY>
<TABLE><TR><TD>
<?php
//In this example the table name to be displayed is static, but it could be taken from a form
$table = "table1";
display_db_table($table, $global_dbh,
TRUE, "border='2'");
?>
</TD></TR></TABLE></BODY></HTML>
Happy coding!
