I am try to create a condition where condition should check the presence of locality or zip code in Multidimensional array, if any one condition is satisfied, its should return true or else false
here is the code i tried with a array
$cars = array("locationabc","locationdef","locationdghi");
$locality = "locationabc";
if ( in_array($locality, $cars) ) {
echo "you can proceed service to your location";
}else {
echo "sorry we don't provide service to your location";
}
but how to do that in multidimensional array, i don''t know whether the below condition is right or wrong
$cars = array
(
array("locationabc",500001),
array("locationdef",500002),
array("locationdghi",500003)
);
$locality = "locationabc";
if ( array_key_exists($locality, $cars) ) {
echo "you can proceed service to your location";
}else {
echo "sorry we don't provide service to your location";
}
I assume that you have multidimensional array as per the example you shown. You can do it like this
$cars = array
(
array("locationabc",500001),
array("locationdef",500002),
array("locationdghi",500003)
);
$locality = "locationabc";
foreach($cars as $car){
if ( in_array($locality, $car) ) {
$msg = "you can proceed service to your location";
break;
}else {
$msg = "sorry we don't provide service to your location";
}
}
echo $msg;
You can use following example to check whether value exist or not-
$flag = 0;
foreach($cars as $c)
{
if(in_array($locality,$c))
{
$flag = 1;
break;
}
}
if($flag == 1)
echo 'value exist';
else
echo 'value does not exist';

<?php
echo "<pre>";
print_r($_POST);
echo "</pre>";
if(isset($_POST['calculate'])) {
// creating an array
$error = array();
if((isset($_POST['buyer']) && is_numeric($_POST['buyer'])) || (isset($_POST['seller']) && is_numeric($_POST['seller']))) {
// setting index
$error ['buyer'] ['0'] = "the byer or seller is not numeric";
$error ['seller'] ['0'] = "the seller is not numericc";
} elseif((isset($_POST['buyer']) && !empty($_POST['buyer'])) || (isset($_POST['seller']) && !empty($_POST['seller']))) {
$buyer = $_POST['buyer'];
$seller = $_POST['seller'];
// here the error comes
} else {
$error ['buyer'] ['1'] = "please input the buyer name";
$error ['seller'] ['1'] = "please input the seller name";
}
if(empty($_POST['product'])) {
$error ['product'] ['0'] = "Please select a Product";
}
// so finally print the array shows the index which i didn't want to start from 1
echo "<pre>";
print_r($error);
echo "</pre>";
// the buyer associative array starts indexing from1
}
?>
This is happening because it's expected behavior. The observed behavior complies with the specification.
Reference: http://php.net/types.array
excerpt:
The key can either be an integer or a string. The value can be of any type.
Additionally the following key casts will occur:
Strings containing valid integers will be cast to the integer type. E.g. the key "8" will actually be stored under 8.
I want to check if a certain field of all rows match a criteria.
So if all rows has in the Status field 'RUN' as value then echo "Success".
If there is one row with END as value then echo "Fail":
I'm guessing I need a loop and an IF statement ?
I was thinking something like this but it doesnt return anything:
while($source_row = mysqli_fetch_array($source_selection)){
if ( ($source_row['Stat']) == ("Run" ) {
echo "Success<br />";
} else
echo "Fail";
}
I don't want to echo each row, I want all rows to match a criteria then echo, if one doesn't match a criteria then echo as well.
This should work for you:
First of all you have to fetch all rows with mysqli_fetch_all(). After this I extract only the Stat column with array_column(). Then I just simply array_fill() an array with X values as you have in $states with the value "Run". And check if every value is equals.
$result = mysqli_fetch_all($source_selection, MYSQLI_ASSOC);
$states = array_column($result, "Stat");
if($states == array_fill(0, count($states), "Run")) {
echo "Success";
} else {
echo "Fail";
}
There are some error in the code and you can use the count to match -
$count = 0;
while($source_row = mysqli_fetch_array($source_selection)){
if ($source_row['Stat'] == "Run" ) {
$count++;
}
}
if($count != mysqli_num_rows($source_selection)) {
echo "Fail";
} else echo "Success";
For best performance you can do it directy on the SQL:
select count(*) from table where Stat <> 'Run';
And then test the returning value to check that is greater than zero.
To do it with php you should know that when you find an error you can stop the iterations. The code would look like that:
while($source_row = mysqli_fetch_array($source_selection)){
if ( $source_row['Stat'] != "Run" ){
$fail = true;
break;
}
}
if ($fail) {
echo "Fail";
} else
echo "Success";
}
Try this
$success=true;
while($source_row = mysqli_fetch_array($source_selection)){
if ( ($source_row['Stat']) != ("Run" ) {
$success=false;
}
}
if ($success) {
echo "Success";
} else {
echo "Fail";
}
My foreach loop:
$empty = "You cannot decommission this truck. It is in use."
$msg = "";
foreach ($trucks_to_remove as $truck_id) {
$truck_id = trim($truck_id);
if (strlen($truck_id)) {
$msg .= decom_truck(
$db,
$depot_id,
$truck_id
);
}
else
{
echo $empty;
}
}
echo $msg;
If the condition is not met, it means the sql cursor that preceded this foreach loop did not return a result for this truck_id (meaning it is in use), I just want a simple message sent to the page to alert the user.
It does not have to be a pop-up or the like. Where would I put my write or print statement? I assume I'd use an else clause but when I add an else inside the foreach loop (see above), I get nothing printed to the page. I have also tried the following:
else if (strlen($truck_id)) == 0
{
echo $empty;
}
I am very new to php.
$arr1 = array();
if(!$arr1)
{
echo 'arr1 is emty<br/>';
$arr2 = array(1, 2);
if($arr2)
echo 'arr2 has data';
exit();
}
I have a code like this
First looping count how many post the array:
for($i = 0; $i < $jumlah_qty ;$i++) {
if(!empty($qty[$i]) && !empty($id_cat[$i])) {
Insert booking:
$insert_booking_hd = $user_class->select($az);
$id_cates = $id_cat[$i];
for($b = 0;$b<$qty[$i];$b++) {
First validation if $_POST[$id_cates) is set run this code:
if(isset($_POST[$id_cates."".$b])){
$id_seat = $_POST[$id_cates."".$b];
Find the seat number in $select_seat and find if seat number is exist in $seat_number:
$select_seat = $user_class->select($query);
$seat_number = $user_class->select($querys);
$row_seat = $user_class->numrows($select_seat);
$row_seat2 = $user_class->numrows($seat_number);
if($row_seat>0) {
$update_seat = $user_class->update($update_false);
$bol[$b] = FALSE;
} else {
if( $row_seat2>0 ) {
$insert_booking_dt = $user_class->insert($insert);
$update_seat = $user_class->update($update_true);
$bol[$b] = TRUE;
} else {
$bol[$b] = FALSE;
}
}
} else {
$insert_booking_dt = $user_class->insert($insert_without_seat);
$bol[$b] = TRUE;
}
if($bol[$b]) {
echo "FALSE";
header("location:../../../print.php?id=$id_booking");
}
else {
echo "WRONG";
header("location:../../../event.php?msg=Same seat number");
}
}
}
}
Anything wrong with my php validation?
Because if I input array of $id_seat it will always redirect to print.php although validation is FALSE
for example if I input 3 array and then I echo FALSE WRONG FALSE FALSE
still redirect to print.php not to event.php
How can I read if one of array is get WRONG and then redirect to event.php?
How can I read if one of array is get WRONG and then redirect to event.php?
You may break out of for-loops.
Instead of:
else {
echo "WRONG";
header("location:../../../event.php?msg=Same seat number");
}
You could try:
else {
echo "WRONG";
header("location:../../../event.php?msg=Same seat number");
break 2;
}
I have a rather big if statement:
if (!$result_spam)
{
$confrim_spam = "FAILED";
}
else if ($result_spam)
{
$confrim_spam = "PASSED";
}
if (!$result_email_manage)
{
$confrim_email_manage = "FAILED";
}
else if ($result_email_manage)
{
$confrim_email_manage = "PASSED";
}
if (!$result_analyt)
{
$confrim_analytics = "FAILED";
}
else if ($result_analyt)
{
$confrim_analytics = "PASSED";
}
Now I want to do another if statement to check if all have PASSED or if all have FAILED or is some have PASSED and some have FAILED and then echo (do something with) the failed ones.
I know how to check if all have passed or failed:
if ($confirm_spam == "PASSED" AND $confirm_analytics == "PASSED"
but to check if some have passed and some haven't and then find the ones that failed will take too long, right?
I was just wondering, would there be an easier/quicker way to do this?
Since they are all bools anyway:
if($result_spam && $result_email_manage && $result_analyt){
//do all passed
}
elseif($result_spam || $result_email_manage || $result_analyt){
//at least one passed
if(!$result_spam){ echo '$result_spam failed';}
if(!$result_email_manage){ echo '$result_email_manage failed';}
if(!$result_analyt){ echo '$result_analyt failed';}
}
else {
//do all failed
}
You can change validation logic to something like
$passed = array();
$failed = array();
if (!$result_spam)
{
array_push($failed, "confirm_spam");
}
else
{
array_push($passed, "confirm_spam");
}
...
Then you have an easy and clear way to check whether all passed/failed and which tests are failed.
What if you try this way:
$passed = $failed = "";
$all = array("confrim_spam" => $result_spam,
"confrim_email_manage" => $result_email_manage,
"confrim_analytics" => $result_analyt);
foreach($all as $a => $b)
{
if (!$b)
$failed.= $a . ", ";
else
$passed.= $a . ", ";
}
Then if var $passed is empty, none passed else if $failed is not empty, at last one have not passed.. so do you got what passed and what failed and do something with them. And you can store results both in a string or an array whatever you want...
