Question

使用postgresql在Ubuntu中工作。

我试图通过带有php的HTML格式在我的postgresql数据库中插入数据。

以下是HTML代码：

<html>
<body>
    <form action="add.php" method="post">
        First Name : <input type="text" name="firstname" size="40" length="40" value="First Name"><BR>
        Surname : <input type="text" name="surname" size="40" length="40" value="Surname"><BR>
        Email Address : <input type="text" name="emailaddress" size="40" length="40" value="Email Address"><BR>
        <input type="submit" name="submit" value="Submit">
        <input type="reset" name="reset" value="Clear It">
    </form>
</body>
</html>

<form action="add.php" method="post">

这是我的PHP文件：

<html>
<body>
    <?php
    $db = pg_connect('host=localhost dbname=postgres user=myusername password=mypassword');

    $firstname = pg_escape_string($_POST['firstname']);
    $surname = pg_escape_string($_POST['surname']);
    $emailaddress = pg_escape_string($_POST['emailaddress']);

    $query = "INSERT INTO friends(firstname, surname, emailaddress) VALUES('" . $firstname . "', '" . $surname . "', '" . $emailaddress . "')";
    $result = pg_query($query);
    if (!$result) {
        $errormessage = pg_last_error();
        echo "Error with query: " . $errormessage;
        exit();
    }
    printf ("These values were inserted into the database - %s %s %s", $firstname, $surname, $emailaddress);
    pg_close();
    ?>
</body>
</html>

我将这些文件放在文件夹\ var \ www \ html \中 Apache正在运行，我已将数据库设置为使用。

当我打开.html文件时，介绍一些数据并点击＆＃34;提交＆＃34;它在编辑器中打开php文件，而不是将数据发送到数据库。我检查数据库，它是空的，没有引入任何内容。

这是按下＆＃34;提交＆＃34;

这里是ports.conf文件的屏幕截图

在apache2.conf文件下面。如果有更多信息需要，请告诉我。我对此很新。我非常感谢你的帮助

# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because     Debian's
# default Apache2 installation attempts to make adding and removing         modules,
# virtual hosts, and extra configuration directives as flexible as        possible, in
# order to make automating the changes and administering the server as easy as
# possible.

# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
#   /etc/apache2/
#   |-- apache2.conf
#   |   `--  ports.conf
#   |-- mods-enabled
#   |   |-- *.load
#   |   `-- *.conf
#   |-- conf-enabled
#   |   `-- *.conf
#   `-- sites-enabled
#       `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
#   together by including all remaining configuration files when starting up the
#   web server.

# * ports.conf is always included from the main configuration file. It is
#   supposed to determine listening ports for incoming connections which can be
#   customized anytime.

# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
#   directories contain particular configuration snippets which manage modules,
#   global configuration fragments, or virtual host configurations,
#   respectively.

#   They are activated by symlinking available configuration files from their
#   respective *-available/ counterparts. These should be managed by using our
#   helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
#   their respective man pages for detailed information.

# * The binary is called apache2. Due to the use of environment variables, in
#   the default configuration, apache2 needs to be started/stopped with
#   /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
#   work with the default configuration.


# Global configuration



# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.

# NOTE!  If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the Mutex documentation (available
# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);
# you will save yourself a lot of trouble.

# Do NOT add a slash at the end of the directory path.

#ServerRoot "/etc/apache2"


# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.

Mutex file:${APACHE_LOCK_DIR} default


# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars

PidFile ${APACHE_PID_FILE}


# Timeout: The number of seconds before receives and sends time out.

Timeout 300


# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.

KeepAlive On


# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.

MaxKeepAliveRequests 100


# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.

KeepAliveTimeout 5


# These need to be set in /etc/apache2/envvars
User ${APACHE_RUN_USER}
Group ${APACHE_RUN_GROUP}


# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.

HostnameLookups Off

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here.  If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.

ErrorLog ${APACHE_LOG_DIR}/error.log


# LogLevel: Control the severity of messages logged to the error_log.
# Available values: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the log level for particular modules, e.g.
# "LogLevel info ssl:warn"

# Sets the default security model of the Apache2 HTTPD server. It does

# These deviate from the Common Log Format definitions in that they use %O
# (the actual bytes sent including headers) instead of %b (the size of the

# Note that the use of %{X-Forwarded-For}i instead of %h is not recommended.
# Use mod_remoteip instead.

Answer 1

pg_query函数中的第一个参数应该是连接，然后是查询字符串。

http://php.net/manual/en/function.pg-query.php

所以：$result = pg_query($db,$query);

更新：

根据新屏幕截图，您的PHP脚本未被执行，因为您遇到了如何配置它的问题。您需要发布有关Web服务器配置的更多信息（Apache，Nginx等）。

好吧，我让它发挥作用。
