php - multidimensional array -


कृपया समझाएं कि 

  foreach ($ toplist ['children'] का अर्थ क्या है $ उपकुंजी = & gt; $ उपनाम के रूप में)

और जहां से बच्चे आए हैं मैं भ्रमित हूँ।

असल में $ toplist मूल्यों की एक सरणी है उन मानों में से एक को 'बच्चों' कहा जाता है।

इस स्थिति में, 'बच्चों' पर स्थित मान ही एक सरणी है।

कोड की आपकी लाइन कंप्यूटर को 'बच्चों' सरणी के अंदर प्रत्येक मूल्य पर लूप के लिए कह रही है और कुंजी और मूल्य को निकालती है।

$ उपकुंजी है कुंजी, $ उपनाम नाम है।

दूसरे शब्दों में, $ toplist ['बच्चों'] [$ subkey] == $ subvalue < / P>

I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
