i receive "echo "Klaida!!!!"" meaning there is no results.
Could you please point out my mistake in code.
$dezesdezesId = $_GET["dezesId"];
$query = "SELECT * FROM dezes WHERE dezesId = '$dezesdezesId'";
$result = mysqli_query($connection, $query);
if (mysqli_num_rows ($result) > 0)
{
while ($row = mysqli_fetch_assoc($result))
{
$dezesPavadinimas = $row["pavadinimas"];
$dezesLikutis = $row["likutis"];
}
echo $dezesLikutis;
}
else
{
echo "Klaida!!!!" . mysqli_error($connection);
}
echo this inside your while loop.
while ($row = mysqli_fetch_assoc($result))
{
$dezesPavadinimas = $row["pavadinimas"];
$dezesLikutis = $row["likutis"];
echo $dezesLikutis;
}
and try to use '{$dezesdezesId}' your variable inside your query string

I'm trying to make an html table with the data in the database but when I write echo it just shows me a result. How can I echo all the elements?
$sql = "SELECT * FROM app_spot where company_id='$company_id'";
$result = mysqli_query($db, $sql);
if (mysqli_num_rows($result) > 0) {
while($row = mysqli_fetch_array($result)) {
$spot_id = $row["id"];
$spot_name = $row["spot_name"];
$store_location = $row["store_location"];
$spot_budget = $row["spot_budget"];
$spot_status = $row["spot_status"];
}
$spotcount = mysqli_num_rows($result);
} else {
echo "0 results";
}
Echo the table rows in the while loop.
if (mysqli_num_rows($result) > 0) {
echo "<table><tr><th>ID</th><th>Name</th><th>Location</th><th>Budget</th><th>Status</th></tr>";
while($row = mysqli_fetch_array($result)) {
$spot_id = $row["id"];
$spot_name = $row["spot_name"];
$store_location = $row["store_location"];
$spot_budget = $row["spot_budget"];
$spot_status = $row["spot_status"];
echo "<tr><td>$spot_id</td><td>$spot_name</td><td>$store_location</td><td>$spot_budget</td><td>$spot_status</td></tr>";
}
echo "</table>";
}
Usually when you do the basic php excercises you just use the following to print data on a blank page:
<?php
include('../includes/dbh.php');
$titulo = mysqli_real_escape_string($conn,$_GET['titulo']);
$sql = "SELECT * FROM proyectos WHERE proyect_name='$titulo'";
$result = mysqli_query($conn, $sql);
$queryResults = mysqli_num_rows($result);
if($queryResults > 0){
while ($row = mysqli_fetch_assoc($result)){
echo "<div>".$row['proyect_name']. "
</div>";
}
}
?>
My question is, if I try to separate and echo out $row proyect_name in another part of the webpage nothing happens. I used both echo and var_dump and yes, the query works but it just doesn't print anything. I am new to this so yes, it may be obvious to you but not to me. I think it may be the while loop, but I do not know how to "blend it in".
<?php
include('../includes/dbh.php');
$titulo = mysqli_real_escape_string($conn,$_GET['titulo']);
$sql = "SELECT * FROM proyectos WHERE proyect_name='$titulo'";
$result = mysqli_query($conn, $sql);
$queryResults = mysqli_num_rows($result);
$data=array();
if($queryResults > 0){
while ($row = mysqli_fetch_assoc($result)){
echo "<div>".$row['proyect_name']. "
</div>";
$data[] = $row;
}
}
foreach($data as value) {
echo $value;
}
// OR
foreach($data as $key => $value) {
echo $key . " - " . $value;
}
?>
Set variable before loop then add $row data to it then loop it out with a foreach loop Does this work??
Use mysqli_fetch_array() - Example
So in your case it would be
<?php
include('../includes/dbh.php');
$titulo = mysqli_real_escape_string($conn,$_GET['titulo']);
$sql = "SELECT * FROM proyectos WHERE proyect_name='$titulo'";
$result = mysqli_query($conn, $sql);
$queryResults = mysqli_num_rows($result);
if($queryResults > 0){
while ($row = $result->fetch_array()){
$rows[] = $row;
}
foreach ($rows as $row) {
echo "<div>".$row['proyect_name']."</div>";
}
}
?>
I am doinga MySQL query to retreive data using PHP. I need to have a logic that if the data set returned is empty it shows a warning message else it displays the results:
$searchQuery = mysql_escape_string($_POST['searchQuery']);
$sql="SELECT * FROM db.tblname WHERE column1 = '".$searchQuery."'";
$result = mysqli_query($conn,$sql);
while($row = mysqli_fetch_array($result)){
echo $row["column1"];
}
mysqli_close($conn);
You need num_rows on the object
$result = mysqli_query($conn,$sql);
if ($result->num_rows == 0) {
echo 'result empty';
} else {
while($row = mysqli_fetch_array($result)){
echo $row["column1"];
}
}
http://php.net/manual/en/mysqli-result.num-rows.php
Change mysql_escape_string to mysqli_escape_string here
$where = "";
if(isset($_POST['searchQuery']) && trim($_POST['searchQuery'])){
$searchQuery = mysqli_escape_string($conn,$_POST['searchQuery']);
$where =" WHERE column1 = '".$searchQuery."'";
}
$sql="SELECT * FROM db.tblname ".$where;
It's as simple as this:
if ($result) {
//Your code
} else {
echo "Error: ".mysqli_error($conn);
}
First check with mysqli_num_rows(). Here is how to
$searchQuery = mysql_escape_string($_POST['searchQuery']);
$sql="SELECT * FROM db.tblname WHERE column1 = '".$searchQuery."'";
$result = mysqli_query($conn,$sql);
if(mysqli_num_rows($result) > 0) {
while($row = mysqli_fetch_array($result)){
echo $row["column1"];
}
}
else {
echo "No records found";
}
mysqli_close($conn);
$searchQuery = mysql_escape_string($_POST['searchQuery']);
$sql="SELECT * FROM db.tblname WHERE column1 = '".$searchQuery."'";
$result = mysqli_query($conn,$sql);
if(mysqli_num_rows($result) > 0) {
while($row = mysqli_fetch_array($result)){
echo $row["column1"];
}
} else {
echo "No results found";
}
mysqli_close($conn);
I want to access while array $row2 outside the loop so that I can compare in if else condition, because $row2 array contains many number. Is there any solution make $row array accessible outside the loop or any other method?
<?php
$sql = (" SELECT * FROM result ");
$query = mysqli_query($db, $sql);
while($row = mysqli_fetch_array($query)) {
$row2 $row['id'];
}
for($i=1;$i<=10;$i++) {
if ($i<= $row2) {
echo "<font color='red'><font size='50px'>".$i."</font></font>"."<br>";
continue;
} else {
echo $i.'<br>';
}
}
?>
If you want to loop over two dependent things you need to nest them or else $row2 will always contain the last value in the while loop:
<?php
$sql = (" SELECT * FROM result ");
$query = mysqli_query($db, $sql);
while ($row = mysqli_fetch_array($query)) {
$row2 = $row['id']; // I added an = sign here.
for($i=1;$i<=10;$i++) {
if ($i<= $row2) {
echo "<font color='red'><font size='50px'>".$i."</font></font>"."<br>";
continue;
} else {
echo $i.'<br>';
}
}
}
If this isn't what you want please clarify your question.
Pass your variable to a separate function that performs whatever task you want.
<?php
while($row = mysqli_fetch_array($query))
{
MyFunction($row2);
}
function MyFunction($passed_row2_value){
// perform whatever task you want here.
}
?>
This shows with some format the ids retrieved by the query and fills the blanks without format.
<?php
$sql = (" SELECT * FROM result ");
$query = mysqli_query($db, $sql);
$row2 = [];
while($row = mysqli_fetch_array($query)) {
$row2[$row['id']] = true;
}
for($i=1;$i<=10;$i++) {
if ($row2[$i]) {
echo "<font color='red'><font size='50px'>".$i."</font></font>"."<br>";
} else {
echo $i.'<br>';
}
}
?>
The query I have below will only show me one result even if there are multiple matching entries (completely or partially matching). How do I fix it so it will return all matching entries:
//$allowed is a variable from database.
$sql = "SELECT `users`.`full_name`, `taglines`.`name`, `users`.`user_id` FROM
`users` LEFT JOIN `taglines` ON `users`.`user_id` = `taglines`.`person_id`
WHERE ( `users`.`user_settings` = '$allowed' ) and ( `users`.`full_name`
LIKE '%$q%' ) LIMIT $startrow, 15";
$result = mysql_query($sql);
$query = mysql_query($sql) or die ("Error: ".mysql_error());
$num_rows1 = mysql_num_rows($result);
if ($result == "")
{
echo "";
}
echo "";
$rows = mysql_num_rows($result);
if($rows == 0)
{
}
elseif($rows > 0)
{
while($row = mysql_fetch_array($query))
{
$person = htmlspecialchars($row['full_name']);
}
}
}
print $person;
Because your overwriting $person on each iteration.
Hold it in a $person[] array if your expecting more then one. Then loop through it with a foreach loop when you intend to output.
Not related but your also querying twice, you only need 1 $result = mysql_query($sql);
Update (Simple Outputting Example):
<?php
$person=array();
while($row = mysql_fetch_array($query)){
$person[] = array('full_name'=>$row['full_name'],
'email'=>$row['email'],
'somthing_else1'=>$row['some_other_column']);
}
//Then when you want to output:
foreach($person as $value){
echo '<p>Name:'.htmlentities($value['full_name']).'</p>';
echo '<p>Eamil:'.htmlentities($value['email']).'</p>';
echo '<p>FooBar:'.htmlentities($value['somthing_else1']).'</p>';
}
?>
Or an alternative way to is to build your output within the loop using concatenation.
<?php
$person='';
while($row = mysql_fetch_array($query)){
$person .= '<p>Name:'.$row['full_name'].'</p>';
$person .= '<p>Email:'.$row['email'].'</p>';
}
echo $person;
?>
Or just echo it.
<?php
while($row = mysql_fetch_array($query)){
echo '<p>Name:'.$row['full_name'].'</p>';
echo '<p>Email:'.$row['email'].'</p>';
}
?>
