Question

我想传入svg箭头图像作为WordPress帖子分页循环的prev_text和next_text。目前，我有localhost urls硬编码。我想设置它，所以这些使用get_template_directory_uri（）或类似。

当前代码：

<?php
  $big = 999999999;

  echo paginate_links( array(
    'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
     'format' => '?paged=%#%',
     'current' => max( 1, get_query_var('paged') ),
     'next_text' => ('<img class="next-arrow" src="http://localhost:8888/mockingbird/wp-content/themes/mockingbird/images/arrow.svg" alt="next posts"/>'),
     'prev_text' => ('<img class="prev-arrow" src="http://localhost:8888/mockingbird/wp-content/themes/mockingbird/images/arrow.svg" alt="previous posts"/>'),
     'total' => $query->max_num_pages
   ) );
?>

我想要的Psuedo代码如下：

'next_text' => ('<img class="next-arrow" src="<?php echo get_template_directory_uri(); ?>/images/arrow.svg" alt="next posts"/>'),
'prev_text' => ('<img class="prev-arrow" src="<?php echo get_template_directory_uri(); ?>/images/arrow.svg" alt="previous posts"/>'),

所以我的问题是，是否可以在数组的字符串中传入php？

如果没有，我如何在没有硬编码的情况下实现这一目标？

通过将next_text和prev_text设置为空字符串，然后将arrow.svg设置为我的CSS中下一个和上一个链接的背景图像，找出解决方案。

这样，我的图片网址就是我的css中设置的相对路径。

#include <iostream>
#include <string>
#include <vector>
#include <sstream>
#include <locale>
using namespace std;

bool palindrome( string, int, int );
bool isAlpha( string );
string charToString( char );
string normalString( string );
char stringToChar( string );
string vectorToString( vector<string> );

int main()
{
    cout << "Enter a word or a sentence: ";

    string str;
    while( cin >> str )
    {
        palindrome( normalString(str), 0, normalString(str).size() - 1 ) ? cout << str << " is palindrome!" << " (" << normalString(str) << ") " 
                                                    << '\n' : cout << str << " is not palindrome!" << " (" << normalString(str) << ") " << '\n';    
        cout << "Enter a word or a sentence: ";
    }
    return 0;
}

string vectorToString( vector<string> vec )
{
    stringstream ss;
    for( int i = 0; i < vec.size(); ++i )
        ss << vec[ i ];
    string str;
    ss >> str;
    return str;
}

string charToString( char c )
{
    stringstream ss;
    string s;
    ss << c;
    ss >> s;
    return s;
}

char stringToChar( string str )
{
    stringstream ss;
    ss << str;
    char c;
    ss >> c;
    return c;
}

bool isAlpha( string s )
{
    return s == "a" || s == "b" || s == "c" || s == "d" || s == "e" || s == "f" || s == "g" || s == "h" || s == "i" || s == "j" || s == "k" || s == "l"||
           s == "m" || s == "n" || s == "o" || s == "p" || s == "q" || s == "r" || s == "s" || s == "t" || s == "u" || s == "v" || s == "w" || s == "x"||
           s == "y" || s == "z" ||
           s == "A" || s == "B" || s == "C" || s == "D" || s == "E" || s == "F" || s == "G" || s == "H" || s == "I" || s == "J" || s == "K" || s == "L"||
           s == "M" || s == "N" || s == "O" || s == "P" || s == "Q" || s == "R" || s == "S" || s == "T" || s == "U" || s == "V" || s == "W" || s == "X"||
           s == "Y" || s == "Z" ; 
}

string normalString( string str )
{
    vector<string> vec;
    for( int i = 0; i < str.size(); ++i )
        vec.push_back( charToString(str[ i ]) );

    for( int i = 0; i < vec.size(); ++i )
    {
        if( !isAlpha( vec[ i ] ) )
            vec[ i ].erase();
        if( isupper( stringToChar(vec[ i ]) ) ) 
            vec[ i ] = charToString( tolower( stringToChar( vec[ i ] ) ) );
    } 

    string str2 = vectorToString( vec );
    return str2;
}

bool palindrome( string str, int first, int last )
{
    if( first == str.size() - 1 ) //if string is a single alphabet.
        return true;
    if( str[ first ] == str[ last ] )
        return palindrome( str.substr( first + 1, last - 1 ), first, last - 2 );
}

CSS：

<?php
  $big = 999999999;

  echo paginate_links( array(
    'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
    'format' => '?paged=%#%',
    'current' => max( 1, get_query_var('paged') ),
    'next_text' => (''),
    'prev_text' => (''),
    'total' => $query->max_num_pages
) );
?>
