Multiple files with HTML and PHP

Question

I’m with an XML file reading system in progress, I chose the language that I do not have as much PHP ease, the fact and that I do not know how to take several files and allocate in a variable, I’m only taking the temporary address of the files and do the reading, all the process that has to be done and shown on the screen is already working but unified, I can only do reading only 1 file by you and need to read several files at a time.

Does anyone know how to read many XML ?

Entry code:

<form action="teste2.php" method="POST" enctype="multipart/form-data">
    <input type="file" name="entXML" multiple="multiple"><br>
    <input type="submit" value="LER_ARQUIVO">
</form>

Treatment with PHP

<?php

//Instanciando o OBJ
 $xml = new DOMdocument();

 //Pegando o TMP do FORM
 $arquivo = $_FILES['entXML']['tmp_name'];

 //Carregando o XML
 $xml ->load($arquivo) or die("Erro ao carregar arquivo XML");



  //Entra dentro do NÓ pai do XML
  $arquivoXML = $xml->getElementsByTagName( "nfeProc" );



//Navegando no Nodes(Nós)
  foreach( $arquivoXML as $xml){

          //Pega Nome
  $nomes = $xml->getElementsByTagName( "xNome" );
  $nome = $nomes->item(0)->nodeValue;
        //Pega CNPJ
  $cnpjS = $xml->getElementsByTagName( "CNPJ" );
  $cnpj = $cnpjS->item(0)->nodeValue;

  //Mostra dados da Tabela EMIT
  echo "<b>Nome:</b> $nome"."&nbsp&nbsp&nbsp";
  echo "<b>CNPJ:</b> $cnpj";

  echo"<br>";
  echo"<br>";
  echo"<br>";


  echo"-------------------------------VALORES----------------------------------";
  echo"<br>";
  //-----------------------------------------------------------------

  //Entra dentro do NODE "ide"
foreach( $arquivoXML as $xml){
        //Pega Numero da NF
          $nfs = $xml->getElementsByTagName( "nNF" );
          $nf = $nfs->item(0)->nodeValue;
        //Pega Data de Emissão da NF
          $dataEMS = $xml->getElementsByTagName( "dhEmi" );
          $dataEmi = $dataEMS->item(0)->nodeValue;
        //Pega CFOP
          $cfopS = $xml->getElementsByTagName( "CFOP" );
          $cfop = $cfopS->item(0)->nodeValue;
        //Pega Valor do XML
          $vaPagS= $xml->getElementsByTagName( "vPag" );
          $vaPag = $vaPagS->item(0)->nodeValue;
        //Pega Status da Sefaz XML
          $motivoS= $xml->getElementsByTagName( "xMotivo" );
          $motivo = $motivoS->item(0)->nodeValue;

//Mostra Tabela na Tela
  echo "<table border=1;>";

      echo "<tr>";
          echo "<th>Nº NF</th>" ;
          echo "<th>Data Emissão</th>" ;
          echo "<th>CFOP</th>" ;
          echo "<th>Valor</th>" ;
          echo "<th>Status</th>" ;
      echo "</tr>";

      echo"<tr>";
          echo"<td>$nf</td>";
          echo"<td>$dataEmi</td>";
          echo"<td>$cfop</td>";
          echo"<td>$vaPag </td>";
          echo"<td>$motivo </td>";
      echo"</tr>";

  echo "</table>"; 
 }
}

Answer 1

If you need to grab multiple files, then you need to treat as an array.

Change the name of adding [] in the end, in this way:

<form action="teste2.php" method="POST" enctype="multipart/form-data">
    <input type="file" name="entXML[]" multiple="multiple"><br>
    <input type="submit" value="LER_ARQUIVO">
</form>

From now on entXML is an array of files and can be recovered in this way:

 //Pegando o TMP do FORM
 $arquivos = $_FILES['entXML']['tmp_name'];

or for example:

 $arquivo1 = $_FILES['entXML']['tmp_name'][0];
 $arquivo2 = $_FILES['entXML']['tmp_name'][1];

In this link should be clearer.

You can try to make a foreach upon the //Carregando o XML, for each position of $_FILES['entXML']['tmp_name'];, for example:

foreach($arquivos as $arquivo) {
    //Carregando o XML
    $xml ->load($arquivo) or die("Erro ao carregar arquivo XML");
    ...
