I want to retrieve each row from one column in one table and put all of them in a element.
I'm pretty much flailing in the dark right now, what am I doing wrong/missing?
$db_connect = mysql_connect("$host", "$db_username", "$db_password");
$db_select = mysql_select_db("$db_name");
mysql_set_charset('utf8', $db_connect);
$db_query_project="SELECT * FROM $tbl_name";
print('<form name="report" method="post" action="">');
print('<label for="project">Projekt </label>');
print('<select name="project_select">');
print('<option>Test</option>');
foreach ($db_query_project as $key => $value){
print('<option>'.$key['project_name'].'</option>');
}
print('</select>');
print('</form>');
Is there a better way to go about doing this?
You need to connect to the database and perform the query in order to retrieve the data and fetch it. To do so, you can use either mysqli or PDO. Here's an example on how to fetch data from a table $tbl_name with a column project_name using mysqli.
$mysqli = new mysqli("localhost", "user", "password", "database");
if ($mysqli->connect_errno) {
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ")";
exit();
}
$query = "SELECT * FROM `$tbl_name`";
if ($result = $mysqli->query($query)) {
/* fetch associative array */
while ($row = $result->fetch_assoc()) {
printf ("%s \n", $row["project_name"]);
}
/* free result set */
$result->free();
}
/* close connection */
$mysqli->close();
i prefer this one:
function getFieldSelect($name, $selected, $values, $attributes) {
$r = "<select name=\"$name\" $attributes>";
foreach ($values as $k => $v) {
if ($k == $selected) {
$sel = "selected";
} else {
$sel = "";
}
$r .= "<option value=\"$k\" $sel>$v</option>\n";
}
$r .= "</select>";
return $r;
}
i got the values from DB and give it to my function in array format. I think this is the most flexible way to print a select field. You can use a database to get the values or any array.
<?php
$db_query_project= mysql_query("SELECT * FROM $tbl_name");
echo '<form name="report" method="post" action="">';
echo '<label for="project">Projekt </label>';
echo '<select name="project_select">';
echo '<option>Test</option>';
while( $row = mysql_fetch_assoc( $db_query_project ) )
{
echo '<option>'.$row['project_name'].'</option>';
}
echo '</select>';
echo '</form>';

How do I echo out every column's data of a row from MYSQL results?
I do not know what the rows are as the query is dynamically created.
Here's what I have:
$query = $_POST['query'];
// Create connection
$con=mysqli_connect($db_host, $db_user, $db_pass, $db_name);
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$results = mysqli_query($con, $query);
while ($row = mysqli_fetch_array($results)) {
}
$row is just an array. Like any other array you can do fun things like iterate over it:
while ($row = mysqli_fetch_array($results)) {
foreach ($row as $key => $value) {
echo 'Key: ' . $key . ', Value: ' . $value;
}
echo "<br><br>\n"
}
Hiii, I am getting multiple value form database when I am using foreach, plz help
function display($host,$user,$pass,$database)
{
$db = mysql_connect($host, $user, $pass);
mysql_select_db ($database);
$query = "SELECT * FROM `sysdes_moduleinfo`";
$result = mysql_query($query) OR die(mysql_error());
$i=0;
while($row = mysql_fetch_array($result))
{
/*$max = count($row);
while($i<6) {
echo $row[$i]." ";
$i++;
}*/
foreach ($row as $value)
{
//echo $value . " ";
echo htmlspecialchars($value);
}
echo "<br/>";
}
This what I get with this code.
.
This what I have in the database.
The default result type for mysql_fetch_array is to return data in both a number and associative array.
This is why data is duplicated. Try using mysql_fetch_row instead.
However it should be noted that both mysql_fetch_array & mysql_fetch_row are both deprecated.
while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
foreach ($row as $value)
{
//echo $value . " ";
echo htmlspecialchars($value);
}
echo "<br/>";
}
mysql_fetch_array returns both a numeric and associative array.
The code below works fine for printing one record from a database table, but what I really want to be able to do is print all the records in the mysql table in a format similar to my code.
I.E.: Field Name as heading for each column in the html table and the entry below the heading. Hope this is making sense to someone ;)
$raw = mysql_query("SELECT * FROM tbl_gas_meters");
$allresults = mysql_fetch_array($raw);
$field = mysql_query("SELECT * FROM tbl_gas_meters");
$num_fields = mysql_num_fields($raw);
$num_rows = mysql_num_rows($raw);
$i = 1;
print "<table border=1>\n";
while ($i < $num_fields)
{
echo "<tr>";
echo "<b><td>" . mysql_field_name($field, $i) . "</td></b>";
//echo ": ";
echo '<td><font color ="red">' . $allresults[$i] . '</font></td>';
$i++;
echo "</tr>";
//echo "<br>";
}
print "</table>";
Just as an additional piece of information you should probably be using PDO. It has more features and is helpful in learning how to prepare SQL statements. It will also serve you much better if you ever write more complicated code.
http://www.php.net/manual/en/intro.pdo.php
This example uses objects rather then arrays. Doesn't necessarily matter, but it uses less characters so I like it. Difference do present themselves when you get deeper into objects, but not in this example.
//connection information
$user = "your_mysql_user";
$pass = "your_mysql_user_pass";
$dbh = new PDO('mysql:host=your_hostname;dbname=your_db;charset=UTF-8', $user, $pass);
//prepare statement to query table
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();
//loop over all table rows and fetch them as an object
while($result = $sth->fetch(PDO::FETCH_OBJ))
{
//print out the fruits name in this case.
print $result->name;
print("\n");
print $result->colour;
print("\n");
}
You probably also want to look into prepared statements. This helps against injection. Injection is bad for security reasons. Here is the page for that.
http://www.php.net/manual/en/pdostatement.bindparam.php
You probably should look into sanitizing your user input as well. Just a heads up and unrelated to your current situation.
Also to get all the field names with PDO try this
$q = $dbh->prepare("DESCRIBE tablename");
$q->execute();
$table_fields = $q->fetchAll(PDO::FETCH_COLUMN);
Once you have all the table fields it would be pretty easy using <div> or even a <table> to arrange them as you like using a <th>
Happy learning PHP. It is fun.
Thanks guys, got it.
$table = 'tbl_gas_meters';
$result = MYSQL_QUERY("SELECT * FROM {$table}");
$fields_num = MYSQL_NUM_FIELDS($result);
ECHO "<h1>Table: {$table}</h1>";
ECHO "<table border='1'><tr>";
// printing table headers
FOR($i=0; $i<$fields_num; $i++)
{
$field = MYSQL_FETCH_FIELD($result);
ECHO "<td>{$field->name}</td>";
}
ECHO "</tr>\n";
// printing table rows
WHILE($row = MYSQL_FETCH_ROW($result))
{
ECHO "<tr>";
// $row is array... foreach( .. ) puts every element
// of $row to $cell variable
FOREACH($row AS $cell)
ECHO "<td>$cell</td>";
ECHO "</tr>\n";
}
while ( $row = mysql_fetch_array($field) ) {
echo $row['fieldname'];
//stuff
}
Try this :
$raw = mysql_query("SELECT * FROM tbl_gas_meters");
$allresults = mysql_fetch_array($raw);
$field = mysql_query("SELECT * FROM tbl_gas_meters");
while($row = mysql_fetch_assoc($field)){
echo $row['your field name here'];
}
Please note that, mysql_* functions are deprecated in new php version , so use mysqli or PDO instead.
Thanks! I adapted some of these answers to draw a table from all records from any table, without having to specify the field names. Just paste this into a .php file and change the connection info:
<?php
// Authentication detail for connection
$servername = "localhost";
$username = "xxxxxxxxxx";
$password = "xxxxxxxxxx";
$dbname = "xxxxxxxxxx";
$tablename = "xxxxxxxxxx";
$orderby = "1 DESC LIMIT 500"; // column # to sort & max # of records to display
// Create & check connection
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error); // quit
}
// Run query & verify success
$sql = "SELECT * FROM {$tablename} ORDER BY {$orderby}";
if ($result = $conn->query($sql)) {
$conn->close(); // Close table
$fields_num = $result->field_count;
$count_rows = $result->num_rows;
if ($count_rows == 0) {
die ("No data found in table: [" . $tablename . "]" ); //quit
}
} else {
$conn->close(); // Close table
die ("Error running SQL:<br>" . $sql ); //quit
}
// Start drawing table
echo "<!DOCTYPE html><html><head><title>{$tablename}</title>";
echo "<style> table, th, td { border: 1px solid black; border-collapse: collapse; }</style></head>";
echo "<body><span style='font-size:18px'>Table: <strong>{$tablename}</strong></span><br>";
echo "<span style='font-size:10px'>({$count_rows} records, {$fields_num} fields)</span><br>";
echo "<br><span style='font-size:10px'><table><tr>";
// Print table Field Names
while ($finfo = $result->fetch_field()) {
echo "<td><center><strong>{$finfo->name}</strong></center></td>";
}
echo "</tr>"; // Finished Field Names
/* Loop through records in object array */
while ($row = $result->fetch_row()) {
echo "<tr>"; // start data row
for( $i = 0; $i<$fields_num; $i++ ) {
echo "<td>{$row[$i]}</td>";
}
echo "</tr>"; // end data row
}
echo "</table>"; // End table
$result->close(); // Free result set
?>
How do I display out all the information in a database (All tables and records) using PHP? I read displaying tables as HTML table but how do I do it for all the tables?
I tried the example here:
http://davidwalsh.name/html-mysql-php
But it shows the table names, how do I also display all the values?
Okay got it .. try this
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "username", "password", "DB");
$result = $mysqli->query("SHOW TABLES");
while ($row = $result->fetch_row()) {
$table = $row[0];
echo '<h3>', $table, '</h3>';
$result1 = $mysqli->query("SELECT * FROM `$table`");
echo '<table cellpadding="0" cellspacing="0" class="db-table">';
$column = $mysqli->query("SHOW COLUMNS FROM `$table`");
echo '<tr>';
while ($row3 = $column->fetch_row()) {
echo '<th>' . $row3[0] . '</th>';
}
echo '</tr>';
while ($row2 = $result1->fetch_row()) {
echo '<tr>';
foreach ($row2 as $key => $value) {
echo '<td>', $value, '</td>';
}
echo '</tr>';
}
echo '</table><br />';
}
$mysqli->close();
you can use the recursive function to display the tree Structure of your database.
Here is the a sample code from http://webcodingeasy.com/PHP/Simple-recursive-function-to-print-out-database-tree-structure
<?php
function print_menu($id = 0)
{
// get all records from database whose parent is $id
$result = $query->select_result("*", "table", "where parent = '".$id."'");
//check if there are any results
if($result != 0)
{
echo "<ul> n";
while($row = $query->fetch($result))
{
//print result and call function to check if it has children
echo "<li>".$row['name']."</li> n";
print_menu($row['ID']);
}
echo "</ul> n";
}
}
print_menu();
?>
If you want to pull all tables with the values in mysql, you can use the following code:
<?php
mysql_connect ("localhost", "DB_USER", "DB_PASSWORD"); //your mysql connection
mysql_select_db('DB_NAME') or die( "Unable to select database"); //your db name
$tables = mysql_query("SELECT table_name FROM information_schema.tables WHERE table_schema='DB_NAME'"); //pull tables from theh databsase
while ($table= mysql_fetch_row($tables)) {
$rsFields = mysql_query("SHOW COLUMNS FROM ".$table[0]);
while ($field = mysql_fetch_assoc($rsFields)) {
echo $table[0].".".$field["Field"].", "; //prints out all columns
}
echo $table[0];
$query = "SELECT * FROM ".$table[0]; //prints out tables name
$result = mysql_query($query);
PullValues($result); //call function to get all values
}
//function to pull all values from tables
function PullValues($result)
{
if($result == 0)
{
echo "<b>Error ".mysql_errno().": ".mysql_error()."</b>";
}
elseif (#mysql_num_rows($result) == 0)
{
echo("<b>Query completed. No results returned.</b><br>");
}
else
{
echo "<table border='1'>
<thead>
<tr><th>[Num]</th>";
for($i = 0;$i < mysql_num_fields($result);$i++)
{
echo "<th>" . $i . " - " . mysql_field_name($result, $i) . "</th>";
}
echo " </tr>
</thead>
<tbody>";
for ($i = 0; $i < mysql_num_rows($result); $i++)
{
echo "<tr><td>[$i]</td>";
$row = mysql_fetch_row($result);
for($j = 0;$j < mysql_num_fields($result);$j++)
{
echo("<td>" . $row[$j] . "</td>");
}
echo "</tr>";
}
echo "</tbody>
</table>";
} //end else
}
?>
I am using this and works fine in mysql, for mysqli you need to tweak it a very little.
I am using a for loop to construct a HTML table from the contents of a MySQL table select query. I have a link on the end of each row to copy that row into another table.
I'm unsure how to get the data from the table row for the MySQL insert query - I have marked the place where I'm struggling with XXX.
<?php
mysql_select_db("cardatabase");
$link = mysql_connect("localhost", "root", "password");
$query = "SELECT * from cars";
$result = mysql_query($query);
if($_GET['rent']) {
$rent = "INSERT INTO rentedcars VALUES('XXX','XXX','XXX','XXX','XXX','XXX','XXX','XXX','XXX','XXX')";
mysql_query($rent);
echo "<meta http-equiv='refresh' content='0;url=rent.php'/>";
}
echo "<table>";
echo "<tr><td>ID</td><td>Make</td><td>Model</td><td>Fuel Type</td><td>Transmission</td><td>Engine Size</td><td>Doors</td><td>Amount</td><td>Available</td><td>Date Added</td><td>Remove</td></tr>";
for ($i = 0; $i < mysql_num_rows($result); $i++) {
$row = mysql_fetch_object($result);
echo "<tr>
<td>$row->ID</td>
<td>$row->CARMAKE</td>
<td>$row->CARMODEL</td>
<td>$row->FUELTYPE</td>
<td>$row->TRANSMISSION</td>
<td>$row->ENGINESIZE</td>
<td>$row->DOORS</td>
<td>$row->AMOUNT</td>
<td>$row->AVAILABLE</td>
<td>$row->DATEADDED</td>
<td><a href='?rent=$row->ID'>Rent</a></td>
</tr>";
}
echo "</table>";
edit (updated code):
<?php
mysql_select_db ("cardatabase");
$link = mysql_connect ("localhost", "root", "password");
$query = "SELECT * from cars";
$result = mysql_query ($query);
if($_GET['rent']) {
$query_car = sprintf("SELECT * from cars WHERE ID=%s",$_GET['rent']);
$rslt = mysql_query($query_car);
$car = mysql_fetch_object ($rslt);
$rent = "INSERT INTO rentedcars VALUES('$car->ID','$car->CARMAKE','$car->CARMODEL','$car->FUELTYPE','$car->TRANSMISSION','$car->ENGINESIZE','$car->DOORS','$car->AMOUNT','$car->AVAILABLE','$car->DATEADDED')";
mysql_query($rent);
echo "<meta http-equiv='refresh' content='0;url=rent.php'/>";
}
echo "<table>";
echo "<tr>";
echo "<td>ID</td><td>Make</td><td>Model</td><td>Fuel Type</td><td>Transmission</td><td>Engine Size</td><td>Doors</td><td>Amount</td><td>Available</td><td>Date Added</td><td>Remove</td>";
echo "</tr>";
while ($row = mysql_fetch_object($result)) {
echo "<tr>
<td>$row->ID</td>
<td>$row->CARMAKE</td>
<td>$row->CARMODEL</td>
<td>$row->FUELTYPE</td>
<td>$row->TRANSMISSION</td>
<td>$row->ENGINESIZE</td>
<td>$row->DOORS</td>
<td>$row->AMOUNT</td>
<td>$row->AVAILABLE</td>
<td>$row->DATEADDED</td>
<td><a href='?rent=$row->ID'>Rent</a></td>
</tr>";
}
echo "</table>";
mysql_* is deprecated as of PHP 5.5.0, you should use something like PDO.
try {
$DBH = new PDO('mysql:dbname=cardatabase;host=localhost', 'root', 'password');
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
$STH = $DBH->query("SELECT * FROM cars")->execute();
while ($row = $STH->fetch(PDO::FETCH_OBJ)) {
echo "<tr>
<td>$row->ID</td>
<td>$row->CARMAKE</td>
<td>$row->CARMODEL</td>
<td>$row->FUELTYPE</td>
<td>$row->TRANSMISSION</td>
<td>$row->ENGINESIZE</td>
<td>$row->DOORS</td>
<td>$row->AMOUNT</td>
<td>$row->AVAILABLE</td>
<td>$row->DATEADDED</td>
<td><a href='?rent=".$row->ID."'>Rent</a></td>
</tr>";
}
Edit: Just like #Skatox said!
I would do it like this:
<?php
$link = mysql_connect ("localhost", "root", "password");
mysql_select_db ("cardatabase");
$query = "SELECT * from cars";
$result = mysql_query ($query);
Get car information and store it
if($_GET['rent'])
{
$query_car = sprintf("SELECT * from cars WHERE ID=%s",$_GET['rent']); //Avoids sql injection
$rslt = mysql_query($query_car);
$car = mysql_fetch_object ($rslt)
Here you need to validate if there's no car
$rent = "INSERT INTO rentedcars VALUES('$car->ID','$car->CARMAKE','$car->CARMODEL','$car->FUELTYPE','$car->TRANSMISSION','$car->ENGINESIZE','$car->DOORS','$car->AMOUNT','$car->AVAILABLE','$car->DATEADDED')";
mysql_query($rent);
echo "<meta http-equiv='refresh' content='0;url=rent.php'/>";
}
Change it to while like #Vinoth Babu said:
while ($row = mysql_fetch_object ($result))
{
$row = mysql_fetch_object ($result);
echo "<tr>
<td>$row->ID</td>
<td>$row->CARMAKE</td>
<td>$row->CARMODEL</td>
<td>$row->FUELTYPE</td>
<td>$row->TRANSMISSION</td>
<td>$row->ENGINESIZE</td>
<td>$row->DOORS</td>
<td>$row->AMOUNT</td>
<td>$row->AVAILABLE</td>
<td>$row->DATEADDED</td>
<td><a href='?rent=$row->ID'>Rent</a></td>
</tr>";
}
print "</table>";
?>
I would recommend you to switch to MySQL PDO, it's safer and you'll get a better and secure code.
you are missing the column names in your insert query
$rent = "INSERT INTO rentedcars (id ,carmake, carmodel,fueltype,transmission, enginesize,doors,amount ,available, dateadded)
VALUES('xxx','xxx','".$carmodel."','XXX','XXX','XXX','XXX','XXX','XXX','XXX')";
^^^^^-------------i showed u exempel under
those XXX are values you get the from the inputs values
exemple
<input name= "car_model" id= "car_model" value="mercedes" >
then you get this value
if (isset($_POST['car_model'])){ $carmodel = $_POST['car_model']}
and then use this value $carmodel in your sql
