php - Trying to query an array -

-

I have a table in which the function has an ID that is in reference to another table named after the function (FinCao in Portuguese , As presented in the code). I want to print the name of all the functions next to that person's name in that function.

Basically the code of the whole program is for the user to write something in a search bar and it is shown, because the user presses a key, the results are shown. Here is the part that is giving me errors (the search_string variable is the field where the user writes.) 

  $ query = 'SELECT * from the users where "%'. $ Search_string '%' '; $ Result = $ tutorial- db- & gt; query ($ query); while ($ result = $ result-> fetch_re ()) {$ result_array [] = $ result;}   
 The above questions take the name of the user.  
  $ query2 = 'Select * Funnel from WHERE id_funcao = "'. $ Result_array ["id_funcao"]. ''; $ Result2 = $ tutorial- db- & gt; query ($ query2); while ($ results2 = $ result2- & gt; fetch_re ()) {$ result_array2 [] = $ results2;}   
 This one takes the ID of the function of that user, and tries to be asked to get the name of the function.  
 Thanks in advance   
 
 
 By joining the easiest way of doing this  
  select utilizadores.nome, Funcoes.funcao Are using funcoes (utilizadores.id_funcao = funcoes.id_funcao) where utilizadores.nome "% & lt;

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
