1) I want to save case 1 value to an array. Return this array and pass it to a function. The code become case 2, but no result come out, where is the problem?
2) In function display_urls, i want to echo both $url and $category. What should i do in IF condition or add another line of code?
function display_urls($url_array)
{
echo "";
if (is_array($url_array) && count($url_array)>0)
{
foreach ($url_array as $url)
{
echo "".$url."";
echo "".$category."";
}
}
echo "";
}
case 1: work fine
$result = oci_parse($conn, "select * from bookmark where username ='$username'");
if (!$result){ $err = oci_error(); exit; }
$r = oci_execute($result);
$i=0;
echo "";
while( $row = oci_fetch_array($result) ){
$i++;
echo "";
echo "".$row['USERNAME']."";
echo "".$row['BM_URL']."";
echo "".$row['CATEGORY']."";
echo "";
}
echo "";
case 2:
$url_array = array();
while( $row2 = oci_fetch_array($result, OCI_BOTH)){
$i++;
$url_array[$count] = $row[0];
}
return $url_array;
I think you probably want something like this:
function display_urls($url_array)
{
echo "";
if (is_array($url_array) && count($url_array)>0)
{
foreach ($url_array as $url)
{
echo "".$url['BM_URL']."";
echo "".$url['CATEGORY']."";
}
}
echo "";
}
$result = oci_parse($conn, "select * from bookmark where username ='$username'");
if (!$result){ $err = oci_error(); exit; }
$r = oci_execute($result);
$url_array = array();
while( $row = oci_fetch_array($result, OCI_ASSOC)){
$url_array[] = $row;
}
display_urls($url_array);
This will store all the information on the URLs in $url_array with a lookup by column name.

I post values to be added to a session array. If a value already exists in the array it should be removed. Both are not resulting in a change of the array.
<?php
session_start();
include_once($_SERVER['DOCUMENT_ROOT'] . '/v5/functions/connect_li.php');
//if (!isset($_session['cart'])) $_SESSION["cart"]= 9;
if (isset($_POST['myresort']) && !empty($_POST['myresort'])) {
$resorts = $_POST['myresort'];
$_SESSION['cart'][] = $resorts;
}
echo '<pre>';
print_r($_SESSION["cart"]);
if (isset($_POST['myresort'])) {
$key = array_search($_POST['myresort'], $_SESSION['cart']);
if ($key !== false) {
unset($_SESSION['cart'][$key]);
$_SESSION["cart"] = array_values($_SESSION["cart"]);
}
}
echo '</pre>';
if (!empty($_SESSION["cart"])) {
echo '<a href="/skirerport/">my resorts: ';
$_SESSION["cart"] = array_unique($_SESSION["cart"]);
$_SESSION["cart"] = array_filter($_SESSION["cart"], 'strlen');
$arr_as_string = implode(',', $_SESSION["cart"]);
$sql = "SELECT resort FROM sv_resorts WHERE res_id IN ($arr_as_string) ORDER BY resort LIMIT 10";
//echo $sql;
$res = mysqli_query($conn, $sql);
while ($ro = mysqli_fetch_array($res)) {
echo $ro['resort'] . " ";
}
print_r($_SESSION["cart"]);
echo "</a>";
}
?>

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 am a completely newbie in programming php I would like to make this code below return many arrays(to flash as3), however I only receive one array.Can anyone please pinpoint what is my mistake here? thanks.
$data_array = "";
$i = 0;
//if(isset($_POST['myrequest']) && $_POST['myrequest'] == "get_characters")
//{
$sql = mysqli_query($conn, "SELECT * FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql))
{
$i++;
$fb_name = $row["Username"];
$fb_id = $row["Fb_id"];
$fb_at = $row["Access_token"];
$fb_sig = $row["Fb_sig"];
$char_id = $row["Char_id"];
if($i == 1)
{
$data_array .= "$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
else
{
$data_array .= "(||)$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
echo "returnStr=$data_array";
exit();
}
When you write your exit insight your loop you stop executing your program and you get only one record. You should set the echo and exit after your while loop.
$data_array = "";
$i = 0;
$sql = mysqli_query($conn, "SELECT * FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql)) {
$i++;
$fb_name = $row["Username"];
$fb_id = $row["Fb_id"];
$fb_at = $row["Access_token"];
$fb_sig = $row["Fb_sig"];
$char_id = $row["Char_id"];
if($i == 1) {
$data_array .= "$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
} else {
$data_array .= "(||)$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
}
echo "returnStr=$data_array";
exit();
Those two last line of your should be outside of your loop:
$data_array = "";
$i = 0;
//if(isset($_POST['myrequest']) && $_POST['myrequest'] == "get_characters")
//{
$sql = mysqli_query($conn, "SELECT * FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql))
{
$i++;
$fb_name = $row["Username"];
$fb_id = $row["Fb_id"];
$fb_at = $row["Access_token"];
$fb_sig = $row["Fb_sig"];
$char_id = $row["Char_id"];
if($i == 1)
{
$data_array .= "$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
else
{
$data_array .= "(||)$fb_name|$fb_id|$fb_at|$fb_sig|$char_id";
}
}
echo "returnStr=$data_array";
exit();
If you would name the columns that you want in the SELECT then it's much simpler. Make sure to use MYSQLI_ASSOC in the fetch:
$sql = mysqli_query($conn, "SELECT Username, Fb_id, Access_token, Fb_sig, Char_id FROM ns_users ORDER BY Char_id");
while($row = mysqli_fetch_array($sql, MYSQLI_ASSOC))
{
$data_array[] = implode('|', $row);
}
echo "returnStr=" . implode('(||)', $data_array);
exit();
I'm trying to print/echo values from previous file however instead of showing error, all that is shown is 'Undefined' on a blank page. I've researched and tried several method but nothing works. Please help.

for undefined mean, there is something which is not existing in global $_POST[]
check try to print $_POST in your first if statement as:
if ($db_found) {
print_r($_POST);
exit();
if (isset($_POST['survey_id'])) {
$survey_id = $_POST['survey_id'];
echo $survey_id;
}
now just see what do you have in $_POST, It might help you...Thanks
Most likely some Post data is not set. Try vardump($_POST); die('happy');.
It would also be better to handle missing Post data instead of just ignoring it so maybe if ($db_found) { should be
<?php
if ( $db_found
&& isset($_POST['survey_id'])
&& isset($_POST['marks'])
&& isset($_POST['id'])
)
{
$survey_id = $_POST['survey_id']; //maybe ensure int
$id = $_POST['id']; //maybe ensure int
$values = array(); //this is important $value will not be available outside the for loop or contain only the last value
foreach ((array)$_POST['marks'] as $value) { //ensure $_POST['marks'] is an array
$values[] = $value; //maybe mysql escape each $value here
}
$SQL2 = sprintf(
"UPDATE answer_table SET marks='%s' WHERE survey_id=%d AND student_id=%d",
impolde(',' $values), //assuming comma separated list here
$survey_id,
$id
);
$result2 = mysql_query($SQL2);
mysql_close($db_handle);
} else { ...
Please also consider to escape the values you read from POST. Doing it this way makes it very easy to SQL inject into your script!
The query I have below will only show me one result even if there are multiple matching entries (completely or partially matching). How do I fix it so it will return all matching entries:
//$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>';
}
?>
