php - array_combine stuck when there is no value in first array -


I am using array_combine () , but this error displays when the first time There is no value in it. First Array distance_are array ([0] = & gt;) School_ID_air array ([0] = & Gt;) and $ coverage using $ array Array = array_combine ($ School_ID_Array, $ Distance_Array); The coverage_array array ([] = & gt;) I think in the first array, if a value is empty, coverage_orize key accepts any default key 

  If you use these conditions: {class = "post-text "Itemprop =" text "// Some codes using $ some_var_or_array value (s)}

UDATED

here The function is ArrayCombine (), which receives three parameters: two arrays and third - Default parameter value will be set to the array values ​​before the empty or nulled: 

  function ArrayCombine ($ array1, $ array2, $ default = 0) {foreach ($ array1 $ key = & Gt; $ value) {if (! Isset ($ value) || Empty ($ value) {$ array1 [$ key] = $ default; }} Return array_combin ($ array1, $ array2); }

Here the example: 

  $ Distance_Array = array (1 = "gt;";); $ School_ID_Array = array (3 = & gt; 4,); $ Coverage_are = arrecombin ($ distance_are, $ School_ID_Array); Var_dump ($ Coverage_Array); / * Var_dump Output: Array (1) {[24] = & gt; Int (4)} * /

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. 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...
