notice

问题 I have been making a script to display users and make changes to their admin privileges. Here is the code: while ($row= mysql_fetch_assoc($query)) { $uname= $row['username']; $fname= $row['first_name']; $lname= $row['last_name']; $email= $row['email']; $admin= $row['admin']; $insert .= '<tr> <td>' .$uname. '</td> <td>' .$fname. '</td> <td>' .$lname. '</td> <td>' .((isset($email)) ? $email:'No email set.'). '</td> <td>'.(($admin == 'y') ? 'Admin':'User').'</td> <td><input type="checkbox" name=

问题 I am using the below code to group the array $summary by currency and get the sum of grouped duration and cost. So far I am able to group and sum the array but since the array cells $result[$split['currency']]['duration'] and $result[$split['currency']]['cost'] are undefined I am getting notice when I run the code. How can I remove the notice without using error_reporting(0) ? Code foreach ($summary as $split) { if (isset($split['currency'])) { $result[$split['currency']]['duration'] +=

问题 I would like to change the '"[product name]" has been added to your basket' prompt to say 'x item(s) has/have been added to your basket'.

And its drive me crazy! Any help is appreciated. My workaround is about customizing that kind of default message : add_filter( 'woocommerce_no_shipping_available_html', 'wf_customize_default_message', 10, 1 ); // For Checkout page add_filter( 'woocommerce_cart_no_shipping_available_html', 'wf_customize

问题 I'm curious as to why I'm getting an error on something I've done a million times before but am all of a sudden on a certain script getting an error 'Undefined variable: row' Yet row seems defined to me... $sql = 'SELECT * FROM table WHERE id="1" LIMIT 1 '; $res = mysql_query($sql); if(mysql_num_rows($res) != FALSE) { $row = mysql_fetch_array($res); } The above is pseudo sql... but I've checked that sql statement and I know its bringing out a result. I also know that $row is storing the data

问题 I am getting Notice: Trying to get property of non-object at: $var = trim($article->find('span[id$=qty]', 0)->innertext); $article is a simple_html_dom() object. 回答1: Maybe span[id$=qty] evaluates to null; means: no node was found. 来源： https://stackoverflow.com/questions/6003991/php-simple-html-dom-notice-trying-to-get-property-of-non-object

问题 I understand that it is a best practice to have all variables defined and to check for array indexes before evaluating. However, I'm trying to run some tests on new functionalities developed on top of some legacy code which has not been coded this way. Behat fails with this message: Scenario: Add a new resource # features/accounting.feature:6 Given I am user "admin" # FeatureContext::iAmUser() Notice: Undefined index: 13 in classloader.php line 126 When I create a new resource #

问题 I'm using Factory in AngularJS, The Script is app.factory('GetCountryService', function ($http, $q) { return { getCountry: function(str) { // the $http API is based on the deferred/promise APIs exposed by the $q service // so it returns a promise for us by default var url = "https://www.bbminfo.com/sample.php?token="+str; return $http.get(url) .then(function(response) { if (typeof response.data.records === 'object') { return response.data.records; } else { // invalid response return $q.reject

问题 If I start a Voice Memo on iOS 8, and go to another app (e.g. Notes) then a red notice appears on the top of the screen (see below, "Recording 00:16"). What is the name of this notice? Where is the relevant iOS documentation? 回答1: You are talking about double-high status bar, this is caused when some other app is recording audio , fetching background locations , etc in background , the double height status bar suggests user that the app is using the resource. You can find relevant docs here

问题 I have a function which uses temporary table, that must be dropped if exists. drop table if exists t_xy; create temp table t_xy on commit drop as select ...; Subsequently I use this function in a view. The function is called many times while select is in progress. I like to use "raise notice" command because it is almost the only reliable way to report any variables in functions for debug purposes.
