executing if condition after a function called in else part. Why? - php

I am checking data if its not exist than insert. so i am using if else condition.
take a glance on code.
if($_POST['save_appointment']){
if(is_user_logged_in()){
$user_appontment_sql = "select * from ".$wpdb->prefix."table where status=1 AND event_id=1 AND user_id=2";
$get_user_data_row = $wpdb->get_row($user_appontment_sql);
if(isset($get_user_data_row)){
echo '<div class="saved_thing">'.__('You have already filled form for appointment for this date').'</div>';
}
else{
$push_form_data=array();
if($_POST['username']){
$user_data=array('username'=>$_POST['username'],'usernamelabel'=>$_POST['usernamelabel']);
$user_name=array('name_data'=>$user_data);
array_push($push_form_data,$user_name);
}
$form_data_all=json_encode($push_form_data);
$done = add_appointment($_POST,$form_data_all);
if($done==true)
{
echo '<div class="saved_thing">'.__('Mange tak. Du hører fra os snarest !').'</div>';
$user_status_mail = "select * from ".$wpdb->prefix."volunteer_app_setting where meta_key='admin_email' OR meta_key='email_send_status' OR meta_key='email_template_accept'";
$get_appointment_send_mail = $wpdb->get_results($user_status_mail);
$event_metadata=unserialize($event_datas_count[0]->pstdata_value);
if($event_metadata['notification_mail']=='1')
{
require_once(dirname(dirname(dirname(dirname(__FILE__))))."/volunteer-appointment/mail/send_mail.php");
$selected_template=$event_meta_data['mail_temp_form_submission'];
$from=$get_appointment_send_mail[0]->meta_value;
$data=array('first_name'=>$_POST['username'],'send_to_admin'=>1,'event_date'=>get_post_meta($_POST['event_id'],'event-date',true),'event_name'=>get_the_title());
$current_user = wp_get_current_user();
$send_mail=mail_user($current_user->user_email,$selected_template,$from,$data);
if($send_mail){
echo '<div class="saved_thing">'.__('E-mail notifikation afsendt til administrator').'</div>';
}
else{
//echo "<script>alert('Mail not send');</script>";
}
}
}
else
{
echo '<div class="saved_thing">'.__('Fejl!!!').'</div>';
}
//}
return;
}
}
}
first we check the data, if its not exist than go to else part.
its is going in if part all the time even data is not exists but saving data . In else part add_appointment() is the issue. this function is saving the data.
I debug
code is checking the condition and if data is not exist in database than go to else part, save data using the function add_appointment() and after executaion of the function again its going to else condition and showing message You have already filled form for appointment for this date

Change your if condition to
from -> if(isset($get_user_data_row))
to -> if(!empty($get_user_data_row))

If no rows are found, it will return 0
if($get_user_data_row > 0) {
// Some code here
} else {
// Some functions here
}

Show if propel successfully deleted related data

I have something like this
$table = TableQuery::create()
->findOneByTableId(1);
foreach($table->getSomeTables() as $item) { // SomeTable is a table linked with foreign-key
$table->removeSomeTable($item);
}
if($table->save()) {
echo "success";
}else {
echo "fail";
}
The problem here is that despite the $table having someTablesScheduledForDeletion and successfully removing it from database when calling method save(), save still returns 0, as if "0 records were changed", though some records are actually deleted.
The same thing goes if I attach more things in a similar way as I did with someTables
What I want to achieve with this is to just get information if these elements were successfully removed
You should just call ->delete() on $item, then you can use ->isDeleted() as intended.
For example:
$table = TableQuery::create()->findOneByTableId(1);
$deleted = 0;
foreach ($table->getSomeTables() as $item) {
$item->delete();
if ($item->isDeleted()) {
$deleted++;
}
}
if ($deleted > 0) {
echo "Rows deleted.";
} else {
echo "No rows deleted.";
}
Issuing another query may be useful. Is there some reason to avoid this?

vTiger Event Handler to check if record exists

I am working on vTiger 6.5 and I am trying to figure a way to see if a record exists in a custom module of mine. I want to check whether the 'policynumber' is new before saving, here is my code so far. For some reason it seems to act randomly depending on my module number chosen.
class isaHandler extends VTEventHandler {
function handleEvent($eventName, $entityData) {
global $adb;
$moduleName = $entityData->getModuleName();
if($moduleName=='isa'){
if($eventName == 'vtiger.entity.beforesave.modifiable') {
$isNew = $entityData->isNew('policynumber');
if ($isNew == false) {
echo "Duplicate policy number";
exit;
}
}
if($eventName == 'vtiger.entity.beforesave') {}}
if($eventName == 'vtiger.entity.beforesave.final') {
$price = $entityData->get('currentamount');
if($price > 20000){
echo "Please go back and enter less than 20000";
exit;
}
if($eventName == 'vtiger.entity.aftersave') {}
}
}
At the moment I am currently using an echo just to see the result. But later on I will perform more than this.
isNew()
Returns true if new record is being created, false otherwise.
More info is here
you should write a custom query to check policynumber already exist or not in your function:
if($eventName == 'vtiger.entity.beforesave.modifiable') {
global $adb;
$result = $adb->pquery("SELECT your-field-name FROM table_name WHERE policynumber=?", array($policynumbervalue));
if($result && $adb->num_rows($result)) {
echo "This policy number exist";
die();
}else{
// write your overwrite code
}
} //end if($eventName == 'vtiger.entity.beforesave.modifiable')
Update:
I am assuming there is field i.e. policynumber in your form, you enter some value in this field and submit the form. so you will get entered policy number value from this:
$policynumbervalue = $entityData->get('policynumber'); //this is vtiger standard way
if this does not work, you can simply use php global variable $_REQUEST['policynumber'] but I is not a good practice.
Hope this will help.
This is the update to my answer, I simply done an if statement on the number of rows displayed.
if($eventName == 'vtiger.entity.beforesave.modifiable') {
$policynumbervalue = $entityData->get('policynumber');
$sql = $adb->pquery("SELECT policynumber FROM vtiger_isa WHERE policynumber=?",array($policynumbervalue));
$nrows = $adb->num_rows($sql);
if($nrows > 0){
echo "<script type=\"text/javascript\">window.alert('ISA policy number already exists, you will be redirected to the updata module.');
window.location.href = '/vtigercrm/index.php?module=isa&view=List';</script>";
exit;
}

How to check if all rows match a criteria in PHP

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";
}

php while loop running only once

I have a php script for check the availability of some data. I call this script from external jquery. the jquery is running fine. here is my php:
<?php
$avares = checkAva($fi_nm, $tbl_nm, $txtval);
echo $avares;
function checkAva($field, $table, $curval) {
$avres = mysql_query("SELECT " . $field . " FROM " . $table . "") or die("query failed");
while ($a_row = mysql_fetch_array($avres)) {
$dbval = $a_row[$field];
if ($curval == $dbval) {
return "no";
} else {
return "yes";
}
}
}
?>
$curval is the variable coming from external jquery. my problem is that the while loop seems to run only once though there are lot of entries in the DB. I checked it with an integer variable and the while loop seems to run only once. can you help me to solve that?
Look at your code.
while ($a_row = mysql_fetch_array($avres)) {
$dbval = $a_row[$field];
if ($curval == $dbval) {
return "no";
} else {
return "yes";
}
}
you have used return, if its true it returns and false then also returns change those according to your needs. The return statement immediately ends execution of the current function
It will by design as you have a return statement. From what you have said your not actually wanting it to return but to set a variable that at end of execution will return no or yes. I could be wrong on this but hey ho.
<?php
echo checkAva($fi_nm, $tbl_nm, $txtval);
function checkAva($field, $table, $curval) {
$avres = mysql_query("SELECT " . $field . " FROM " . $table) or die("query failed");
$noOrYes = "yes";
while ($a_row = mysql_fetch_array($avres)) {
if($curval == $a_row[$field]) {
$noOrYes = "no";
}
}
return $noOrYes;
}
?>
The possible issue that can cause Loop to iterate once are:
Error in the Variable used for the $query and $result
Same name Variable inside and outside of the Loop
Incorrect placement of Return statement
Invalid Mysql Statement
Directly put the condition in your Query like
function checkAva($field, $table, $curval) {
$avres = mysql_query("SELECT " . $field . " FROM " . $table . "
WHERE `".$field."` = '".$curVal."'");
$res = mysql_fetch_array($avres);
if(is_array($res) && count($res) > 0)
return "Yes";
else
return "No";
}
Instead of getting all the results and checking with each one of the result you directly put a condition to extract the results which satisfies your condition.This will be suggestable if you have many records.
You need to put one of the return outside of the while loop.
For example if you just wanted to check if $curval == $dbval
while ($a_row = mysql_fetch_array($avres)) {
$dbval = $a_row[$field];
//If the condition was met return with a no
if ($curval == $dbval) {
return "no";
}
}
//If the condition was not met return yes
return yes;
That's basically what you need to do so the loop will run until your condition was met or not at all.

how to restrict the value entered in a textbox based on the value entered in the previous one in php

I have 2 textboxes one is for maximum marks and the other for the obtained marks..
The value to be entered in the second box must be restricted in such a way that it is less than or equal to the maximum marks.. Only numbers must be entered into those boxes..
Maximum Marks<input type=text name=maxmarks maxlength='2' >
Obtained marks<input type='text' maxlength='2' name='obtmarks'>
Please help me with this.. Thank you in advance..
Well if you want to do it client side, you will have to use Javascript. If you want to do it server-side, why don't you send them back the page with an error message if the second number exceeds the first. You might also might want to look into HTML5 input options if that is an available option for you. Those will automatically do the number validation.
You could try something like this...
$response_array = array();
if($obtained > $max){
$response_array['status'] = 'error';
$response_array['message'] = '<div class="alert alert-error">Obtained to big</div>';
}
if(!is_numeric($obtained){
$response_array['status'] = 'error';
$response_array['message'] = '<div class="alert alert-error">Obtained not a number</div>';
}
echo json_encode($response_array);
This is pseudo code, obviously you will need to tweak it for your purpose.
First you have to make checks in your php script that you submit the form, you can use javascript after to make it more user friendly but if someone change the source code or just turn javascript off he will be able to submit anyting.
In your process_form.php:
session_start();
$errors = array();
if (!isset($_POST['maxmarks']) || empty($_POST['maxmarks'])) {
$errors[] = 'The Maximum Marks field is required.';
}
else {
if (!is_int($_POST['maxmarks'])) {
$errors[] = 'The Maximum Marks field must be an integer.';
}
else {
$maxmarks= (int) trim($_POST['maxmarks']);
}
}
if (!isset($_POST['obtmarks']) || empty($_POST['obtmarks'])) {
$errors[] = 'The Obtained Marks field is required.';
}
else {
if (!is_int($_POST['obtmarks'])) {
$errors[] = 'The Obtained Marks field must be an integer.';
}
else {
$obtmarks= (int) trim($_POST['obtmarks']);
}
}
if (!empty($errors)) {
$_SESSION['form_errors'] = $errors;
header('Location: your_form.php');
die();
}
else if ($obtmarks > $maxmarks){
$errors[] = 'The Obtained Marks must be less or equal to Maximum Marks.';
$_SESSION['form_errors'] = $errors;
header('Location: your_form.php');
die();
}
else {
//process data
}
In your_form.php now:
session_start();
if (isset($_SESSION['form_errors']) && !empty($_SESSION['form_errors'])) {
$errors = $_SESSION['form_errors'];
unset($_SESSION['form_errors']);
}
echo '<ul>';
if (isset($errors)) {
foreach($errors as $error) {
echo '<li>' . $error . '</li>';
}
}
echo '</ul>';
//your form here
